HTTP::header insert

I have implemented the following iRuel to add a httpheaders.

 

 

when HTTP_REQUEST {

 

HTTP::header insert BESPOKEHEADER "value"

 

}

 

 

It adds the header fine but the value is always blank

 

 

any ideas ?

 

 

BIG-IP 9.1.1 Build 54.6

 

 

Reason for adding this is we have 2 Virtual servers set up on our load balancer. One for https requests and the other for non secure request.

 

 

The servers behind the load balancers allways receive a http request as SSL is now handled by the load balancers.

 

 

Our applications can no longer use check the headers for SSL as request.servervariables["https"] =="off" always evaluates to true.

 

 

So i have added the http header "BESPOKEHEADER" using this iRule to the https virtual server. hope this all makes sence.

    Hi,

     

     

    The rule is simple enough and should work. I tested on a 9.2.3 unit and see in a tcpdump that the header and value are added:

     

     

    P...<...GET./.HT

     

    TP/1.1..User-Age

     

    nt:.curl/7.10.6.

     

    (i686-redhat-lin

     

    ux-gnu).libcurl/

     

    7.10.6.OpenSSL/0

     

    .9.7i.ipv6.zlib/

     

    1.1.4..Host:.htt

     

    p_vip..Pragma:.n

     

    o-cache..Accept:

     

    .image/gif,.imag

     

    e/x-xbitmap,.ima

     

    ge/jpeg,.image/p

     

    jpeg,.*/*..BESPO

     

    KEHEADER:.value.

     

    ...

     

     

    Note the BESPOKEHEADER: value at the end.

     

     

    Are you sure that you're not seeing the header and value added? Is it possible it's being added, but the server isn't parsing it as expected?
