[Chameleon] Moving an application dir ...

Wed Mar 1 11:16:16 EST 2006

Hi Julien,

After following your suggestions, Ive managed to get the application working
about 90% on the new disk. I can now get the scalebar, n.arrow and legend
images to draw. The only problem that remains is that the images associated
with the widgets display as broken links. When I check the properties of
these broken images, it would appear that the url's are correct, also the
images that the urls point to exist in the directory where they should.
However they dont make it to the browser window. If you have any more
thoughts Id like to hear them.

	The reason for my attempt to relocate the map app to another disk is
because we would like to seperate the application and its data from the web
and map server. The rational is that this will increase security when the
site goes live. Can you (or anyone on the list) advise on the following.
Will this move of the application to a seperate disk improve the security?
Can you think of a better way to increase the security of ms4w/chameleon
install? I have searched on the keyword 'security' on the MS site but cannot
find specific recommendations of securing such an application. Have I missed
essential documentation?

Once again, Thanks for all of you help!
Jeremy

Hi,
Since only the buttons are missing, you may try to check the source of 
what is produced by Chameleon to see from where it try to get the 
image.Is it possible that the button_cache_web_path is not properly 
configured in chameleon.xml?

chdir() before everything else in the index.phtml.

The drive letter hardcoding should be done in every configuration file 
(chameleon.xml, index.phtml, php.ini)
