opening blocked urls with ?java

[rachit0286]

i study in a college and thus naturally behind a proxy server that has a firewall which blocks all urls containing certain strings such as mp3,chat.........and so on.......

But we can access all these urls by just appending them with ?java
For example: http://www.***mp3***.com will give an access denied message but
http://www.***mp3***.com?java will simply open the site as if it was just any other site.

Why does this happen?

I don't know but have you tried other stuff? I'm sure it's not just java, you can probably put ?justaboutanything there :P. Interesting, and something you may want to let someone know about. Peace.

Sounds to me like they are either using a very week proxy to block sites, or they ar just blocking specific addresses. If the ip that hosted the offending network was blocked it certianly wouldn't load because of a ?java added at the end of a URL. You might send the network admin an email, wheter or not you let them know who you are is up to you, explaining the flaw in their security. Depending on the admin this might cause them to have a hissy fit. But in the long run you would be doing them a favor.

I did try using other strings but it seemed to worl only with ?java and ?javascript
