Flash Chart Performance Problem behind Firewall

Question

I am running into an issue with running Flash based charts behind a firewall.
Database: 11.1.0.6
Apex: 3.1.2.00.02 (Using Oracle HTTP Server via Oracle Application Server)
Flash: 3.1.2.00.02
I have a page the displays a 2D Line graph with three data series. When I run the report directly against my app server (URL: [http://ecydblcyorwq06/public/f?p=128:11]
where ecydblcyorwq06 is my app server) the chart displays just fine. In
order for the public to access this page they must go through our
firewall called fortress. So they start by accessing the system from [https://fortress.wa.gov/ecy/wplcsreports/,] which then maps to my application (128:1). The URL becomes [https://fortress.wa.gov/ecy/wplcsreports/public/f?p=128:1].
When I try to run the chart through fortress it never renders. I just
get the "Loading Data...Please Wait" progress bar. The progress bar
moves very slowly and never returns the chart.
My dads.conf looks like
<Location /public>
SetHandler                  pls_handler
Order                       deny,allow
Allow                       from all
AllowOverride                  None
PlsqlDatabaseUsername        APEX_PUBLIC_USER
PlsqlDatabasePassword         xxxxxxxx
PlsqlDatabaseConnectString  database_server:1521:my_sid     SIDFormat
PlsqlAuthenticationMode       Basic
PlsqlDefaultPage                  f?p=wplcs_online:permit_search
PlsqlDocumentTablename     wwv_flow_file_objects$
PlsqlDocumentPath             docs
PlsqlDocumentProcedure     wwv_flow_file_mgr.process_download
PlsqlNLSLanguage            AMERICAN_AMERICA.AL32UTF8
</Location>My Apache httpd.conf file looks like:
<VirtualHost *>

RewriteEngine On
RewriteRule ^/$ /public/f?p=wplcs_online:permit_search [R]

HTTP/1.1" 200 80216Is there something that I need to do from the configuration standpoint
to make the chart work across the firewall? Do I need to do something
with the Virtual host definition so that the XML file works properly?

Answer 1

Alright, I have modified my DAD to include the following line:
PlsqlCGIEnvironmentList HTTP_HOST=fortress.wa.gov/ecy/wplcsreports:80
I restarted the OHS and how I get an XML error in the chart region.
XML Loading Failed: http://fortress.wa.gov/ecy/wplcsreports/public/apex_util.flash?p=128:11:......The thing I noticed here is that the failed URL is not HTTPS, but HTTP instead. I am guessing this is the current problem. So I went back to my httpd.conf file and tried to add the request_method directive to my virtual host definition, but this just caused the OHS restart to fail.
httpd.conf
<VirtualHost *>
ServerName wplcsreports
RewriteEngine On
RewriteRule ^/$ /public/f?p=wplcs_online:permit_search [R]
DocumentRoot /www/pls/apex
#RewriteCond %{REQUEST_METHOD} ^TRACE
Port 80
</VirtualHost>So how do I force the XML file loading to be under the HTTPS protocol?
