getting url path from known absolute path

[enfantterrible-tijzQ7]

Is there a CF 8 function that will give me the url path for an a known OS absolute path.

For example if I have a path to a file or directory like:

C:\Inetpub\wwwroot\ccradius\public\applications\cruzcontrol\uploads\uploadpics\badday1.jpg

OR

C:\Inetpub\wwwroot\ccradius\public\applications\cruzcontrol\uploads\uploadpics\

Thanks for any help!!!

No, there's no such function.  It's a bit tricky to automate because a directory on the file system could be mapped in any number of ways on the CF server, and there's no automatic way for CF to second-guess which mapping you'd want to be using.

Basically what you need to do is to use expandPath() to expand a mapping that you want to use to resolve the file system path into a URL, and then look for a match of that in the path you are trying to convert.  If it's there, chop the file system path accordingly (and flip the slashes around if needs must).

EG:

Your path:

C:\Inetpub\wwwroot\ccradius\public\applications\cruzcontrol\uploads\uploadpics\b adday1.jpg

Your root mapping:

/ => C:\Inetpub\wwwroot\ccradius\

So expandPath("/") resolves to C:\Inetpub\wwwroot\ccradius\

Now use replace() to get rid of that bit of the path from your target path:

public\applications\cruzcontrol\uploads\uploadpics\b adday1.jpg

Prepend the mapping (which is just "/" in this case):

/public\applications\cruzcontrol\uploads\uploadpics\b adday1.jpg

Use replace() to substitute the \ with /

/public/applications/cruzcontrol/uploads/uploadpics/b adday1.jpg
