Compression iRules - GZIP vs. Deflate Preference

F5 DevCentral,

 

 

Hi, our understanding is that when doing a Profile that utilizes Compression that BIGIP will prefer the Deflate vs. GZIP method. We would like to have a rule that utilizes GZIP by default.

 

 

The current rule we are using to do this is:

 

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

 

b rule force_gzip '{ when HTTP_RESPONSE { [COMPRESS::method prefer gzip] }}'

 

 

which gives us

 

 

[rootxxxxxxx:Active] config b rule list

 

rule force_gzip {

 

when HTTP_RESPONSE { [COMPRESS::method prefer gzip] }

 

}

 

 

When we then associate this rule with a VIP we get an error.

 

 

 

ERROR in /var/log/ltm

 

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

 

Mar 25 22:31:03 tmm tmm[702]: 01220001:3: TCL error: Rule force_gzip - invalid command name "" while executing "[COMPRESS:

 

:method prefer gzip]"

 

 

 

Do you have any ideas what we might be doing wrong?

 

 

Thanks,
