Compression when request has a query string?

Are you compressing by URL or Content Type?

I've removed the content section, so just URI, which is default at .*

Can you post the profile CLI configuration output please? I always use Content Type which keeps things fairly simple.

I've changed it round to be content-type, as that makes more sense I think.

The config is this:

ltm profile http-compression V2QA_DefaultCompression {

app-service none
buffer-size 1048576
content-type-exclude none
content-type-include { text/* application/javascript application/x-javascript application/* }
defaults-from wan-optimized-compression
gzip-level 6
uri-exclude none
uri-include none

}

I see it compressing CSS, which we also feed a query string, but still not the JS files.

Many thanks for your help!

Hmmm. Looks OK.

Can you do a quick tpcdump (or use HTTPHeaders or something similar at the browser end) to see if the responses that are not compressed have a Content-Type header?

If they don't you may need to switch back to URI and add * to the end of the URI types (.js rather than *.js).

Headers look OK to me - this is from Fiddler, response headers:

HTTP/1.1 200 OK Content-Type: application/javascript Last-Modified: Fri, 04 Jul 2014 12:42:24 GMT Accept-Ranges: bytes ETag: "dfdb99678597cf1:0" Date: Thu, 10 Jul 2014 15:38:41 GMT Transfer-Encoding: chunked

Accept encoding headers also there in the request?

Also, do you have Chunking: Selective in the HTTP profile.

Sorry, things keep coming to mind as we go.

it wasn't, but it is now with no change on compression.

request header is :

Accept-Encoding: gzip,deflate,sdch

Odd. Is it because the .js files are tiny perhaps?

Again, have you tried switching back to URI and using .jpg?
