Hi Julien,
Unfortunatly, I currently dont have access to to the IIS server that is 'in
front of' the apache server. Nor do I have acces to the logs. Im working on
getting access to those. When/if I do, can you recommend and configuration
specifics I should check on the IIS server? As I mentioned, IIS is the proxy
for the Apache/ms4w server. In the apache error log, I dont see any mention
of the main map image.
Here is what the apache log reports when I attempt to access the app from
WAN, php doesnt seem to be reporting any errors:
[Fri Mar 17 14:49:56 2006] [error] [client xxx.xxx.xx.xx] Fri Mar 17
14:49:56 2006 - msFreeHashItems(): Hash table error. Can't free NULL
table\r, referer: https://WAN.address/dir2/cwfis/fireactivity_e.php

And this is what I get when accessing the same from LAN (this one works)

Hi,
Did you check the error log of Apache and IIS? You should see the exact
request to the image. That should give you good hints. Does the path to
the image in IIS _and_ Apache config are visible from the web?
