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.
Aaron- Thanks Aaron,
we will try the new rule tomorrow.....
Btw, we are running V9.4.4 plus HF1
Patrick - Hi Aaron,
it works! perfect!
Thx again,
Patrick - 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. - Good to know...thanks!
