proxy

Sunday, July 7, 2013 0 comments
In  computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Today, most proxies are web proxies, facilitating access to content on the World Wide Web.

Types of proxy

A proxy server may run right on the user's local computer, or at various points between the user's computer and destination servers on the Internet.
  • A proxy server that passes requests and responses unmodified is usually called a gateway or sometimes a tunneling proxy.
  • A forward proxy is an Internet-facing proxy used to retrieve from a wide range of sources (in most cases anywhere on the Internet).
  • A reverse proxy is usually an Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching.

Forward proxies

A proxy server connecting an internal network and the Internet.
A forward proxy taking requests from an internal network and forwarding them to the Internet.
Forward proxies are proxies where the client server names the target server to connect to.[4] Forward proxies are able to retrieve from a wide range of sources (in most cases anywhere on the Internet).
The terms "forward proxy" and "forwarding proxy" are a general description of behavior (forwarding traffic) and thus ambiguous. Except for Reverse proxy, the types of proxies described in this article are more specialized sub-types of the general forward proxy concept.

Open proxies

Main article: Open proxy
An open proxy is a forwarding proxy server that is accessible by any Internet user. Gordon Lyonestimates there are "hundreds of thousands" of open proxies on the Internet.[5] An anonymous open proxy allows users to conceal their IP address while browsing the Web or using other Internet services. There are varying degrees of anonymity however, as well as a number of methods of 'tricking' the client into revealing itself regardless of the proxy being used.

Reverse proxies

A proxy server connecting the Internet to an internal network.
A reverse proxy taking requests from the Internet and forwarding them to servers in an internal network. Those making requests connect to the proxy and may not be aware of the internal network.
Main article: Reverse proxy
A reverse proxy (or surrogate) is a proxy server that appears to clients to be an ordinary server. Requests are forwarded to one or more origin servers which handle the request. The response is returned as if it came directly from the web server.[4]
Reverse proxies are installed in the neighborhood of one or more web servers. All traffic coming from the Internet and with a destination of one of the neighborhood's web servers goes through the proxy server. The use of "reverse" originates in its counterpart "forward proxy" since the reverse proxy sits closer to the web server and serves only a restricted set of websites.
There are several reasons for installing reverse proxy servers:
  • Encryption / SSL acceleration: when secure web sites are created, the SSL encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware. See Secure Sockets Layer. Furthermore, a host can provide a single "SSL proxy" to provide SSL encryption for an arbitrary number of hosts; removing the need for a separate SSL Server Certificate for each host, with the downside that all hosts behind the SSL proxy have to share a common DNS name or IP address for SSL connections. This problem can partly be overcome by using theSubjectAltName feature of X.509 certificates.
  • Load balancing: the reverse proxy can distribute the load to several web servers, each web server serving its own application area. In such a case, the reverse proxy may need to rewrite the URLs in each web page (translation from externally known URLs to the internal locations).
  • Serve/cache static content: A reverse proxy can offload the web servers by caching static content like pictures and other static graphical content.
  • Compression: the proxy server can optimize and compress the content to speed up the load time.
  • Spoon feeding: reduces resource usage caused by slow clients on the web servers by caching the content the web server sent and slowly "spoon feeding" it to the client. This especially benefits dynamically generated pages.
  • Security: the proxy server is an additional layer of defense and can protect against some OS and Web Server specific attacks. However, it does not provide any protection to attacks against the web application or service itself, which is generally considered the larger threat.
  • Extranet Publishing: a reverse proxy server facing the Internet can be used to communicate to a firewall server internal to an organization, providing extranet access to some functions while keeping the servers behind the firewalls. If used in this way, security measures should be considered to protect the rest of your infrastructure in case this server is compromised, as its web application is exposed to attack from the Internet.

Porte-bébé ou poussette : comment bien choisir ?

0 comments


                    Pour promener votre enfant, il n’est pas toujours évident de choisir entre un porte bebe et une poussette. Tous les deux ont des avantages, mais aussi des inconvénients.

La poussette simple et la poussette double pour les balades

D’une part, la poussette bébé est pratique, car elle vous permet de ne pas devoir porter tout le temps votre enfant. Cela vous évite des problèmes de dos prématurés et elle est d’autant plus avantageuse qu’elle peut être couverte en cas de pluie. De plus, si vous avez des jumeaux, vous trouverez facilement une poussette double qui vous permet de transporter vos bébés en même temps sans devoir être deux. En effet, imaginez un peu la contrainte si vous devez sortir deux poussettes à chaque fois que vous voulez vous promener avec vos enfants. Vous seriez obligés d’attendre le retour de votre conjoint pour vous balader. Avec une poussette double, le problème ne se présente pas puisque les deux bébés peuvent aller dans une seule poussette en même temps,ce qui vous permettra ainsi de vous promener tous les trois ! La poussette, qu’elle soit simple ou double, est donc très pratique pour les promenades. Néanmoins, elle a l’inconvénient de ne pas être facilement transportable. En effet, elle prend beaucoup de place dans le coffre de la voiture ou dans son entrée de maison. De plus, avec la poussette, vous n’avez pas les mains libres, ce qui peut être contraignant si vous avez plusieurs choses à faire en même temps.

Le portebebe pour avoir les mains libres

Le porte bebe, quant à lui, n’a pas cet inconvénient : il se range très facilement et ne prend pas de place. Ainsi, vous pouvez l’emmener partout sans devoir prévoir une place supplémentaire pour son rangement. Néanmoins, il présente l’inconvénient que vous devez toujours porter votre bébé. N’oublions cependant pas que c’est pratique, car cela permet d’avoir les mains libres. On peut donc continuer à faire ses activités normalement, tout en ayant son enfant dans ses bras. Malheureusement, à terme, vous pourrirez avoir des problèmes de dos à cause du poids permanent de votre enfant. Par conséquent, il faut choisir un porte bebe uniquement pour les petits trajets ou lorsque vous êtes à l’intérieur afin de pouvoir vous asseoir souvent et limiter la charge constante du poids de votre enfant.

N’oubliez pas lachambre de bebe !

Bien évidemment, la poussette ou le porte bebe ne sont pas les seuls produits qu’il vous faut pour vote progéniture. Par exemple, vous pouvez acheter un collier ambre bebe qui a la faculté d’apaiser votre enfant grâce aux bienfaits de la pierre et des huiles qui le recouvrent. Pensez aussi à bien choisir votre table a langer ou le matelas bebe dans la chambre de bebe. Les nouveaux parents doivent penser à la qualité des matériaux qui les composent ainsi qu’à la sécurité pour l’enfant. De nos jours, les matelas bebe sont anti-allergènes pour éviter les problèmes et les chambres de bébés sont disponibles avec des matériaux robustes limitant le risque d’échardes. C’est la même chose pour la table a langer ou le collier ambre bebe. Ils sont spécifiquement adaptés pour votre enfant et limitent tous les risques dans le cadre d’une utilisation normale, pour vous sentir en confiance en ce qui concerne la sécurité de votre tout-petit.
A propos de l'auteur : Kadolis propose le collier ambre bebe qui possède la propriété d’apaiser votre enfant grâce à l’action bienfaisante de la pierre et de l’huile qui le recouvrent. Ce tout nouveau produit incontournable ravit tant les mamans que les enfants. Mais si vous cherchez plutôt une table a langer, le site propose aussi toute la gamme qu’il vous faut.

What Is in Royal Jelly?

Tuesday, July 2, 2013 0 comments
                         Are you wondering what is in royal jelly? To begin understanding this natural super-food, you should know what it is. It can be described as a special substance manufactured by worker bees. Naturally they produce this milky substance, also called bee's milk, to raise their queen bee and her larvae. Young female bees are fed with this substance until they are strong enough to share responsibilities in the beehive. They eat jelly for a few days only though. Some of them are intended to become queens later on. So they are fed bee's milk continually and remain safe in the hive. The source of bee's milk is the glands located on top of the worker bee's head. It boasts a white, creamy texture.
Research and studies about the benefits of queen bee food for humans have been done for many years now. Unfortunately, there is no conclusive evidence that this substance can heal, prevent or alleviate symptoms of diseases. Experiments that have been conducted so far to determine the components of royal jelly have revealed the following about it. It is very high in amino acids, sugars, proteins, lipids and vitamins. It is particularly the best source of vitamin D and E. These two elements are very essential to human health. If you are looking to consume more of B vitamins, royal jelly has B1, B2 and B6 - based on the U.S. Department of Agriculture's research.
In addition to this, this milky substance is a source of folic acid, inositol, biotin, pantothenic acid and niacin. As a result, royal jelly's rich content is thought to cure many human disorders. Some people describe the healing powers of this bee product as miraculous. I do not know if you have a similar testimony too. Just because of eating royal jelly daily, the queen's lifespan is sixty times longer compared to the drone's (male bee). She also grows bigger, heavier and stronger than any other bee in the hive. Because of this, humans harvest this milky stuff from the hives to benefit the same way the queen bee does.
Royal jelly is linked with the alleviation of symptoms of chronic and severe diseases. These include cancer, arthritis, weak kidneys, bad cholesterol, bad skin, impotence, low libido, female infertility, allergies and high blood pressure among others. According to scientists, sugars, fats, proteins, B vitamins, folic acid and niacin are responsible for these changes. For the purpose of improving health, royal jelly is sold in form of pills or capsules. These supplements must be consumed daily to enhance health, according to providers.
Royal jelly is hard to collect in large amounts from the hives. This is why supplements are manufactured. Before taking any of these supplements, bear in mind that they are not regulated by any American health or food association. Its use and benefits are based on the fact that various experiments on rats have so far shown positive results. Now that you know what is in royal jelly, and diseases it can improve, you should look for it. Perhaps it is just what you require to solve your health issues. Beware that royal jelly also has side effects in some users.
Royal jelly is considerd to be a real fountain of youth and health. If you are interested in how to use this hive product you can find here more useful information http://thebenefitsofroyaljelly

How I Lost 10lbs in 10 Days

Monday, July 1, 2013 0 comments
                 I have been battling my weight for more than a decade, and have finally found the long sought for answer that I dreamed of finding. I found the answer on how to lose 10lbs in 10 days. The fact is it was not that difficult and it did not cost me a fortune. It did not take very much effort at all. I just changed a few of my bad habits and set out on a mission to lose weight and I succeeded.
I was like you, unhappy with my appearance, and I really wanted my clothes to fit and look good on me. I sought to be attractive again and to rebuild the self-esteem that had been plummeting for quite sometime. Every time I looked in the mirror I wanted to cry the weight was everywhere and my face looked bloated and unhealthy as well.
This aspect made me consider what I wanted to put into my body, and well truth is it was not viable foods that were contributing to this factor. The junk, the sweets, eating out, preservatives, and more were all what had gotten me to the point where my entire body was just not healthy in general. If you really consider losing 10lbs in 10 days it cannot be that difficult. I mean we all know there is no magic pill that works, sure we can control our hunger with pills, but people always want what they cannot have.
This is where my idea came to life. I had to possess a distinguishing trait that causes most people to fail at weight-loss- will power. People surrender to their whims and indulge in gluttony in their life constantly. Perhaps if we step away, and make a few adjustments to these habitual rituals in eating and our everyday lives the change itself will occur. It did! I changed a few things and ate more than I ever thought I could. I was not hungry, but I had to trade my thought patterns and mind tricked myself to not wanting the sweets, pastas, and yummy foods that are so tempting. Also one has to get passed the peer pressure which is one of the leading causes of diet and weight-loss failures.
Have not you heard your peers say well one taste will not hurt or you can eat lunch here with us they have a diet menu. Truth is one taste leads to others and most people see the tempting menus and disregard the diet menu at all costs. Once you are there it is all over. However, you can simply lose 10lbs in 10 days by reading, researching, and teaching yourself good habits and that every choice that you make effects the fact that you pass or fail at your goal of losing 10lbs in 10 days.
Please visit the lose ten pounds site for resources and facts on how you too can achieve the once thought of unobtainable.
