The compression statistic for 'Other' content increases unexpectedly when compressing javascript content
Misleading compression statistics
This issue occurs when: - Virtual with compression profile - HTTP responses received with a Content-Type header value other than 'application/x-javascript'
Use iRule to change Content-Type header: when HTTP_RESPONSE { if {[HTTP::header Content-Type] contains "text/javascript"} { HTTP::header replace Content-Type application/x-javascript log local0. "after [HTTP::header Content-Type]" } }
HTTP bodies containing a Content-Type header of 'application/javascript' or 'text/javascript' will be recorded under the 'Javascript' compression statistic.
