Corporate Proxy Servers
As a general definition, corporate proxy servers (and school proxies too) are applications that work as a gateway to transmit data between inner (trusted) network and outer network that is possibly not safe. There are some benefits for companies from using proxy servers:
Less expences on internet connection
Instead of using individual internet connection for every PC in the network, the company share internet connection through the proxy servers. Proxy servers help to reduce cost due to the fact that there can be hundreds even thousands of PC’s in the network. IP addresses are allocated dynamically, according to needs. Company’s proxies distribute local IP addresses between the PC’s.
Data caching
Proxy servers can also cache some of the most commonly accessed data. Data caching is used to reduce the need to access data from remote hosts This save the bandwidth and reduce time to access websites. Data caching is being used by the most of internet providers too.
Proxy servers act as firewalls
Due to their design, proxy servers can also act like firewalls and block any unwanted access to the company’s inner network. Proxy server can be configured to allow only certain information to reach the company’s network and other access restrictions. From that point network administrators can manage internet access for company’s employee. They can block access to certain websites e.g. Myspace, Facebook, etc. These restrictions are defined by company’s internet access policy
would like to log onto msn or msn2go or fxmessenger but am being blocked by work firewalls. I have tried going through privacy surf.com but then it says at the respective site you need javascript my pc has java onit?
I have checked MSN2Go website. Yes, you need at least Java 1.4 to be installed to run new MSN2Go. Keep in mind that Java is not the same as Java script. Basically you need to download and install special software package to use Java. I doubt you can do this at your work.
The bad news is that neither MSN2Go nor other web messengers do not work through proxy websites. That’s because of heavy client-side scripting they use. I’ve tried a number of methods and various types of proxy but I got no luck.
I suggest you to search for similar IM services. There are lots of them on the net. Try to search ‘web IM’ on google. I’m sure you will find one that works at your place.
I really enjoyed this post. I will definitely check back later for more informative posts from you. Thanks!
