Compression iRules - GZIP vs. Deflate Preference

So based on all of the changes we talked about, I just want to double-check that I now have the right rule rule that removes the original rule + does the GZIP check in the ACCEPT-ENCODING Header.

 

 

I removed the original rule and I am assuming that the "exist" function will scan the entire header and thus instead of matching "Accept-Encoding" we can just match on "gzip". If there's no GZIP then no need to rewrite anything.

 

 

Would this rule incorporate everything we talked about so far?

 

=================================================================

 

rule gzip2 {

 

when HTTP_REQUEST {

 

if {[HTTP::header exist "gzip"]} {

 

HTTP::header replace "Accept-Encoding" "gzip"

 

event disable

 

}

 

}

 

}
