BIGIP 9.0.3 trying to configure compression iRule command

 

Trying to configure compression iRule command, receiving PCL error.

 

(Due to customers displaying PDF)

 

 

 

 

Also, here are the relevant Microsoft KB for the Internet Explorer problems handling compression:

 

 

For IE 5.5 : http://support.microsoft.com/default.aspx?scid=kb;en-us;Q313712

 

 

For IE 6.0 : http://support.microsoft.com/default.aspx?scid=kb;en-us;Q312496

 

 

And the KB article that lead to need to write the Remove_No_Cache_Headers iRule

 

 

http://support.microsoft.com/default.aspx?scid=kb;en-us;323308

 

 

 

 

 

Rule used:

 

 

 

 

Here’s on iRule I tried, with selective compression enabled in the HTTP profile:

 

 

when HTTP_REQUEST {

 

set hdr_user_agent [string tolower [HTTP::header User-Agent]]

 

if { $hdr_user_agent contains "firefox" or $hdr_user_agent contains "msie 6.0" } {

 

set client_ok 1

 

log local0. "Header agent $hdr_user_agent compressed"

 

}

 

else {

 

set client_ok 0

 

}

 

}

 

 

when HTTP_RESPONSE {

 

set hdr_content_type [string tolower [HTTP::header Content-Type]]

 

if { $hdr_content_type contains "text" or $hdr_content_type contains "message" } {

 

if { $client_ok == 1} {

 

log local0. "Trying to compress response type $hdr_content_type for $hdr_user_agent"

 

COMPRESS::enable

 

}

 

}

 

}

 

 

 

 

 

And a second rule tried, again enabling selective compression in the HTTP profile and also configuring a content type list in the HTTP profile:

 

 

when HTTP_REQUEST {

 

set hdr_user_agent [string tolower [HTTP::header User-Agent]]

 

if { $hdr_user_agent contains "firefox" or $hdr_user_agent contains "msie 6.0" } {

 

COMPRESS::enable

 

log local0. "Header agent $hdr_user_agent compressed"

 

}

 

}

 

 

 

 

Result using the iRule:

 

 

Both result in the F5 unit responding to the HTTP GET with a TCP RST, and logging the following error:

 

 

TCL error: Rule Selective_Compression - Error: Unknown error (line 1) invoked from within "COMPRESS::enable"

 

 

Any ideas what may be wrong?
