I have one interesting question which confuse me a lot today since I learn something new in BIGIP. My questions are: 1:If I removed one header in HTTP profile,but add same header back in irule,...
application delivery
devops
iRules
LTM

    I give it a test:

    root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm profile http customer_http 
ltm profile http customer_http {
    app-service none
    defaults-from http
    header-erase Headertest
    proxy-type reverse
}

root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list ltm rule http_header_test 
ltm rule http_header_test {
    when HTTP_REQUEST {
        HTTP::header insert "Headertest" "123"
}

    }

    Then test with curl 10.1.1.73 -H "Headertest: 123", from the capture it shows http header Headertest still in the request.

Hi,Stephan suppose I want to compress uri starts with /xyz[any-thing-behind] ,what is the right uri list and content list to achieve this? From my test,uri list and content list compose the exact object F5 will compress.

 

For example,if I only add /xyz.* in uri list while leave content list unconfigured,F5 doesn't compress .... I am confused by this....

    Hi Robbie, what TMOS version are you using and do you want to split control on compression between http/acceleration profile and iRule? Thanks, Stephan
