Try using software that was built specifically for reverse proxying..
http://www.apsis.ch/pound/ is a really good one that we use that handles
the HTTPS (port 443) to HTTP (your port 8080) translation just fine.
With so much of the Mid-Tier stuff being Java-based, it is much easier
to use a reverse proxy program than to make a web server (Apache) handle
the reverse proxy.  We use Pound for a couple different Java apps and it
works really good.

Subject: Proxy Apache Web Server to Tomcat issues

 

** We are working on bring up a new web server.  We want to use Tomcat
for the JSP engine and run a full Apache web server as the front end as
an app firewall and for static content.  We have tried various
combinations of mod_proxy, mod_rewrite and even tried mod_proxy_html.

We want to proxy traffic on :443/arsys to :8080/arsys on the same
server.  Static pages work fine, our proxy for :443/rkm to :8080/rkm
works and even the Mid-Tier configuration works from
:443/arsys/shared/config/config.jsp to
:8080/arsys/shared/config/config.jsp.

We also tried setting up a ProxyFilter section in C:\Program Files\AR
System\Mid-Tier\WEB-INF\web.xml as suggested in "Configuring Apache
2.0.x to work as a Proxy server using mod_proxy on UNIX"
(KM-000000025464) without any success (after restarting Tomcat).
When we try to access an actual Remedy form, the new 7.1 Loading icon
sits in the middle of the page and nothing ever happens, not an even
timeout.  We have set the MT logs to Fine and watching the logs do not
show any activity during this Loading period (no looping).

The last line of the log if access by :8080 directly or through Apaches
:443 is:

Dec 9, 2008 12:11:38 PM - FINE (com.remedy.log.SERVLET) :
server:<servername>||app:null||form:Home Page||view:Support
View||file:||appResource:null||size:3


Opening the same URL path from :8080/arsys is 93 lines and :443/arsys is
only 30 lines (let me know if you wish to see the missing content, this
posting is getting long enough without it)

Has anybody else running a full Apache front end had these kinds of
issues?
Any suggestions as to the proper way to configure this type of setup (I
am not terribly Apache literate)?

Environment
----  firewall (only allowing 443 from the cloud) ----
Web Server
OS: Window 2003
JSP Engine: Tomcat  5.5.26  Port 8080
Web Server: Apache 2.2 Port 443
Mid Tier 7.1 patch 3

----  DMZ  ----
ARS Server
OS: Window 2003
DB. MS SQL 2005
ARS 7.0.01 patch 6

Thanks,
Jason
