[users@httpd] Re: How to preserve all request headers in reverse proxy (mod_proxy)
Actually, I'm not even sure what I'm trying to do is possible - can someone
confirm that I'm attempting something that can be done? :)
Basically, I have foo.war and bar.war and own the foo.com and
bar.comdomains. I want to deploy the two web-apps in Tomcat on port
8080 and have
httpd send http://www.foo.com/ to http://localhost:8080/foo/ and
http://www.bar.com/ to http://localhost:8080/bar/ so that each web-app looks
like its own top-level web-app in its own domain. Is this doable, 'cause I
can't seem to find anyone out there who's done it :)

Haha - the problem is I'm an idiot :) Your message made me go back and
check my assumptions, and sure enough, I took stupid pills today.
I had created a test page that spits out the request headers in HTML, and I
checked the page in Firefox bypassing the proxy, then checked it *by
telnetting to port 80* using the proxy. Of course there were no user-agent
request headers when I used telnet! I saw the lack of request headers and
thought "the proxy is dropping them!"
<sheepish-grin/>,

What's the problem?
The rules for which request headers are passed through are determined
by the HTTP standard, not by Apache. In some cases you have choices,
documented in the mod_proxy_http page.
If you tell us what's really the problem, maybe someone can help.
