RegEx not behaving as expected

Hello, all,

I think I may have posted regarding this issue, before, but didn't get any response; I (unfortunately) have to try, again.

I am using a Regular Expression to map the full physical location on the HD of where the website is located.  I need this for a CFFILE tag.

The reason I'm using a RegEx instead of hard coding the location is because the location varies depending upon whether it is being used in development, staging, or production.  (Yeah, I know.. all three should be mirrors of each other - I'm working on that.  )

For example, our DEV environment needs the CFFILE tag to point to E:\ColdFusion10\cfusion\wwwroot\www\ folder.

Our staging environment needs the CFFILE tag to point to C:\ColdFusion10\cfusion\www\ folder.

Our production environment needs the CFFILE to point to F:\webdocs\cf\www\docs\ folder.

I really do NOT want to be hackish about this and use a CFIF or CFSWITCH to set the "this.webrootmapping" variable.  Besides, if anything gets changed, I'd have to go in and change the code.  Not ideal.

So, I'm using a RegEx.  I'm also setting it so that it will always point to the ROOT, no matter what sub-folder the user is in.

What I have (and isn't working for the production environment) is:

<cfset this.webrootmapping = REreplaceNoCase(ExpandPath('./'),
           '(.+[\\|\/]www([\\|\/]docs)?[\\|\/])(.+)',
           '\1',
           'all') />

What this is supposed to do is accept everything up to the "www" folder, or up to "www\docs" folder, and remove everything after that.

It's working in dev and staging; it is NOT working in production (where the root ends in "\docs\".)  The question mark should be indicating "zero or one of \docs".  But it isn't.

Any insight greatly appreciated.

V/r,

^_^
