Hi !

Need your support to resolve following scenario:-

We have squid proxy server working perfectly ok. For content management we have installed Squidguard over it. This also is working okay. The sites/URLs which were supposed to be blocked are getting blocked.

The users have come with a new technique -- Users log in to site www.way2sms.com. Once logged in , the site gives options for opening Yahoomail and Gmail ( which are actually blocked in our scenario).

The URL displayed in the address bar at this stage does not have any mention of Yahoo/Gmail. If we block the URL displayed, it stops way2sms.com domain also which is required by us.
How can we restrict this kind of activity so that users are not able to go to Yahoo or Gmail sites ?

Thanks In Advance

Well it certainly is evidence of a fscked up situation if users slash employees aren't allowed to use webmail but texting is considered "vital" but OK. As you've found the address bar is unreliable to determine anything so best bypass the proxy and use your own (Privoxy?) for troubleshooting as you only need to log requests, log into the account, notice the link that provides access to Gmail then access it. I doubt the site would proxy requests but knowing the link and what requests are sent after accessing the link gives you a better view of what's happening.

Thanks for your response !

Can you please give step by step guidance to carry out the same ?

Sure. Exactly what step that you actually have tried performing are you having problems with?

What is privoxy ? how to use it ?

It's proxy software. It has got its own web site so finding instructions shouldn't be hard to find using LQ search or your favorite search engine. You only need it to determine requests made. Alternatively you could use Opera/Dragonfly Firefox/Firebug to log those.
