Re: weird logs showing up

[alex black]

I have a theory,
(I didn't recompile because I'm using the debian package and because  
ngrep allows me to fully debug the request/responses).

I poured over monit's requests. There is only one significant  
difference:

Host: www.myhost.com:80.

It's adding the port number.

I tested this theory, and I was right:

telnet www.myhost.com 80
GET /catalog/list.php HTTP/1.1.
Host: www.myhost.com

Returns exactly what I would expect, a bunch of HTML.

telnet www.myhost.com 80
GET /catalog/list.php HTTP/1.1.
Host: www.myhost.com:80

Returns a 302.

Thus the problem.

I think my server is "right" - i.e. it's saying "don't use the :80.

So, how can I stop monit from appending the :80 to the host header?

:)
