Content List Compression, Regex Patterns/Matching

Device: LTM/BigIP 3600

 

Version: BIG-IP 10.2.0 Build 1707.0 Final

 

 

Q:

 

 

Can anyone confirm that, in HTTP Profiles with Content List Compression, compression for content type "text/" ONLY matches "text/" and not partial matches, (e.g. "text/css", "text/javascript", etc...) if no regular expressions (regex) patterns are specified?

 

 

 

Hi,

 

 

I know that the HTTP Profile Context Help doesn't describe pattern matching, but the description under 8(b) in the LTM Manual under Compression in HTTP Profiles - http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_implementation/sol_http_compress.html1062118 - illustrates patterns:

 

 

"8.

 

...

 

b)

 

compression.

 

Examples of content types that you can specify are application/pdf and image/**."

 

 

From this, it seems reasonable to assume that the defaults of:

 

 

text/

 

application/(xml|x-javascript)

 

 

only match exactly that, and not text/**.
