http-proxy to apache failed.

I have an apache server running on port 82.

//proxy for apps

}).listen(80);   

when i request http://www.xxxx.com/a/b
it always redirect to http://www.xxxx.com:82/a/b
Because of firewall. it will failed.
why port 82 will be shown up?

huh, that's weird, it definitely shouldn't redirect in your browser. That would require sending back a 300 redirect and stuff, which is a little crazy, are you sure apache isn't sending back a 300 redirect?

I am not very familiar with apache.
Once I used nginx as front. it can work well with apache2.

Also I google it, and find there are same issues about this. like
http://comments.gmane.org/gmane.comp.lang.javascript.nodejs/22110

[coderarity]

Yeah, that's what I thought. Apache is sending back a redirect, like that guy says in that thread you sent. In that thread, he did state the solution:

I've found that the port number only appears when the URL points to a
directory but lacks a trailing slash. This means that I can write some
Node.js code to check the URL and, if necessary, do a 301 redirect to
a fixed URL. I haven't had time to implement this yet, but I think it
will solve the problem.

(indexzero also provided an example in response to that, check it out here)

thank you, i use another ip address for apache2. So currently my problem is resolved.
