I am not technically an Appeon developer, however we have a
working Application that we are trying to protect by
implementing a reverse proxy in a DMZ. Currently when a user
connects with a browser directly, the application loads in
under 15 seconds. However, when the traffic is directed
through our reverse proxy, the load time increases to over
40 minutes.

The reverse proxy is working very well for other web sites
that handle basic HTTP or HTTPS calls, as well as for Web
Service requests. Are there other considerations that we
need to address for the Appeon application? Ports that need
to be open besides 80 and 443?

I have already opened a service call with the vender of the
reverse proxy software, but I wanted to also see if any
thoughts, ideas, suggestions could be produced from this
forum.

Version: Appeon 5.1.03.06.00
OS: Windows Server 2003 sp 2
Platform: Sybase EA Server - Jaguar

Thanks in advance - DaveH

Hi Dave,

Since we have not seen the Reverse Proxy, so we are not sure
about the exceptions or settings, but at a high-level, you
need to make sure HTTP and the port you are using are open
and that it is not filtering or stripping out anything (for
example it should allow all files/data to pass through
rather than just limit it to HTML and JavaScript files).

Regards
Sally

The reverse proxy software is IBM WebSphere Edge Components Caching
Proxy. I got information from IBM that I needed to add this directive
to make it work faster:

SendHTTP10Outbound https://my.url.here/*

I am not sure why sending HTTP 1.0 is faster than HTTP 1.1 requests.
But it worked great. Maybe someone out there knows why Appeon responds
better with HTTP 1.0 - anyone?

Thanks for listening to me rant - DaveH
