http::host is not populated

Hi,

 

 

If you send a request 'GET /test.html' to the VIP, you aren't including the Host header, so the redirect will be to https://test.html. If you make a request using 'GET /test.html HTTP/1.0\r\nHost: test.example.com' the HTTP::host command will return test.example.com. I would guess that the web server is assuming a default host value for the request.

 

 

You could add a check to the iRule which redirects to the VIP's IP address if no host is specified. Or if you know that clients can be redirected to a single domain, you could hard code it.

 

 

Here is an example of the first option:

 

 

when HTTP_REQUEST {
    Check if Host header value has a length
   if {[string length [HTTP::host]]}{
       Redirect to the requested host
      HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
   } else {
       Redirect to VIP's IP address
      HTTP::redirect https://[IP::local_addr][HTTP::uri]
   }
}

 

 

If you wanted to hardcode the domain for redirects when the Host header doesn't have a value, just change [IP::local_addr] to the host you want.
