* a request made by ntop internally, or from an ntop .html page which you had to
* be root (or the ntop userid) to install in the first place...
*
* 1. We need to check whether the URL is invalid, i.e. it contains '..' or
* similar chars that can be used for reading system files.
* 2. We can't check the password - we no longer have the Authorization header.
* Besides, we already authorized the page request.
* 3. Strip leading /s and trailing white space
* 4. Break the URI into URI and PARM, then
* 5. Actually process it...
*
* Lastly, remember ssiRequest (and pointers to it) is a COPY, so we don't have
* to restore characters we null out. But, once we do so, we can't display the whole
* request!
