Embedded IP inside HTTP packets

[hsalleeh () hotmail com]

Hello,

Some of the HTTP packets contains IP Addresses inside the payload 
so, I want to get it ? how and using what? 
I know I can do it by decoding the HTTP payload using the RFCs as I did in other protocols BUT I couldn't find any RFC 
that describe the format and the structure of the payload. if you know these RFCs ( explains these info. ) please refer 
me to it. 

if there is any solution , using snort or any thing please help me 
I am using snort with MySQL 
Thanks in advance
