CFBlog Administrator Blog

I use Apache's mod_rewrite quite often for other projects I work on besides Blogfusion. I recently upgraded a client site to use SES urls for all of their dynamic pages, but ran into a bit of a bug when it came to some of the Flash Forms in their administrative area of the site, specifically the <cfgrid> tag.

In mod_rewrite, you can use a Rewrite Condition in your .htaccess file or <VirtualHost> block like the following to stop any further processing of rewrite rules if the URI matches any of the parameters. I usually place a block at the top of my .htaccess file that looks something like this:

#Escape the following in the URI using pipe delimiter for strings
RewriteCond %{REQUEST_URI} ^jrunscripts|CFIDE|admin.+$
RewriteRule .* - [L]

I added the CFIDE and admin directory, which according to the source output off the the Flash object and javascript being written by CF, should have handled all of the missing directories. Unfortunately, the problem continued. After several hours of searching and digging through technotes, I finally found this unrelated technote about a problem with IIS, which contained following to provide a clue:

"Create a directory named 'CFFormGateway' under the IIS webroot. You may leave this newly created directory empty."

By jove, I think I've got it! So I changed the Rewrite Condition to:

#Escape the following in the URI using pipe delimiter for strings
RewriteCond %{REQUEST_URI} ^jrunscripts|CFIDE|CFFormGateway|admin.+$
RewriteRule .* - [L]

Bingo! CFGRID is back online...

For the most part, placing the above (minus the "admin" string, unless it applies) should allow mod_rewrite and Coldfusion Flash Forms to work and play nice together.
