http-https redirect adds Server header

Hi all,

 

I have an issue with an irule which redirects http traffic to https.

 

The irule works fine, but my customer has concerns about the Server header he sees with liveheaders:

 

 

 

HTTP/1.x 302 Found

 

Location: https://www.xxxx.xx/

 

Server: BigIP

 

Connection: Keep-Alive

 

Content-Length: 0

 

 

 

I tried the http::header insert command to modify this entry, but nothing changes here.

 

 

Now, why do we set this Server header? and is there a way to modify it within this redirect?

 

 

Thanks for your help here.

    I can't find the solution which describes this, but it's expected behavior when using HTTP::respond or HTTP::redirect in older LTM versions. You can use a workaround for HTTP traffic (Click here😞 

     
 TCP::respond "HTTP/1.1 302 Found\r\nLocation: https://[HTTP::host][HTTP::uri]\r\nConnection: close\r\nContent-Length: 0\r\n\r\n" 
 TCP::close

    I think it's been changed in recent versions but didn't find anything about it in the 9.4.x release notes.

    For HTTP, that workaround will be OK, but not for HTTPS. Starting in 9.4.2, you can add the "noserver" keyword to HTTP::respond, and it will suppress the "Server: BIG-IP" header.

     

     

    I haven't updated the DevCentral docs with the rest of the 9.4.2+ information (detailed at http://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&postid=17481&view=topic); been way too busy.
