Hi Kalpesh,

 

 

You can get the value of the referer header (or any other HTTP header) using [HTTP::header value Referer].

 

 

http://devcentral.f5.com/wiki/iRules.http__header.ashx

 

 

Note that any HTTP header value can be spoofed by a malicious client. And most HTTP user agents will not send a referer if they are coming from an HTTPS site.
