enable compression if parameter exists in content type

Question

Newbie here. I'm trying to compress data with content type "text/html;charset=UTF-8". I do not want to compress the data if the parameter is missing i.e content type "text/html" should not be compressed but "text/html;charset=UTF-8" should. &nbsp;
&nbsp;I've tried using the following rule but without success. &nbsp;
&nbsp;when HTTP_RESPONSE {
&nbsp;   set content_type [string tolower [HTTP::header Content-Type]]
&nbsp;   if { $content_type contains "text/html;charset=UTF-8"}{
&nbsp;COMPRESS::enable
&nbsp;}
&nbsp;}

change UTF in your if statement to utf since you are converting the content type information to lowercase.

Thanks for the responses...
&nbsp;The following rule worked. &nbsp;
&nbsp;when HTTP_RESPONSE {
&nbsp;   if { [HTTP::header Content-Type] contains "charset"} {
&nbsp;COMPRESS::enable
&nbsp;  }
&nbsp;}&nbsp;
&nbsp;Neither "text/html;charset=UTF-8" nor "charset=UTF-8" worked. 
&nbsp;Are ";" and "=" considered as special characters that need to be escaped?&nbsp;
