Is VCL meant to handle port numbers in HTTP Host headers more
gracefully? I was trying to check my varnish configuration by calling
the nagios-plugins check_http utility, and to get it to work I had to
add line 3 in the following:
1 sub vcl_recv {
2 if (req.http.host == "www.trinitycollege.vic.edu.au" ||
3 req.http.host == "www.trinitycollege.vic.edu.au:80") {
4 set req.backend = backend;
5 }
Here is some output from varnishlog that shows that the check_http
program formats it's Host header with a port number.
7 RxRequest c GET
7 RxURL c /
7 RxProtocol c HTTP/1.1
7 RxHeader c Host: www.trinitycollege.vic.edu.au:80
7 RxHeader c User-Agent: check_http/v1991 (nagios-plugins 1.4.12)
7 RxHeader c Connection: close
I thought that was a bit odd, but apparently it's permitted in RFC 2616.
I wonder if varnish should decode such a header to something like:
req.http.host = "www.trinitycollege.vic.edu.au"
req.http.hostport = "80"
Is this worth a bug report?
