Re: Re: Blocking Yahoo Messege in SQUID

Hi Henrik,

Thanks for responding to the mail.

Yahoo Messegenger works on YMSG Protcol which is wrapped under HTTP. When anyone sends an IM, at comm.c:comm_write(), I am able to filter out "FROM" and "TO" field of the messege, from there I connect to MySql and check whether IM is allowed between "FROM" and "TO", if not then I have to block it, but since I am not able to block, so I redirect it to another yahoo id by replacing the "TO" field.

You were pointing to some higher level of design, can you suggest me the right place to hook to get the "FROM" and "TO" field and at same time can modify the content length or block the entire packet.

Regards
Sharat

Allow list where?

Too low level. You need to look higher up in the design.

Can you roll back a little and describe at HTTP protocol level what it is
you want to do?

Is this request or response data?

Is it a HTTP request, or data within a CONNECT request?
