Content length after compression

Hi.

 

Does anyone know of a way to get HTTP content length after compression has been completed?

 

We're running Big-IP 10.2.4 currently and the HTTP_RESPONSE event gives the uncompressed size of an object from the pool member by reading the HTTP Content-Length header.

 

With Big-IP 11.x there's a HTTP_RESPONSE_RELEASE event which I think would do the job but unfortunately we're not running that release.

 

It's for bandwidth monitoring of content types and sizes.

 

Cheers.

    As Nitass says, until you get to v11, VIP-targeting is probably you're best bet. 

    
 Outer VIP:
when HTTP_REQUEST {
virtual internal.vip.vs
}
when HTTP_RESPONSE {
log local0. [HTTP::header Content-Length]
}
