To have a quick look at the urls that are easily available within the
REQUEST namespace create a dtml method in the 'end' folder that contains:
Then point your browser at this method (eg.
http://www.mywebsite.com/folderA/folderB/tstmethod) and see what comes up.
Once you have located a variable that gives you what you need, you can
easily access it via something like: REQUEST['URL0'] or REQUEST['BASE3'].
If the path (url) you need is not located within the REQUEST namespace then
you may need to work-around the problem... one possibility is to create
property field on the 'top' level folder that contains the base url you
need. You can than access this property field to build the required url.
