I don't know exactly how are you doing this thing.
If you're joining 2 files it's very easy to add a space at the top of
them without extra work (disk access etc...) but only if you use
clever tools.
Since you can't be sure of the cleverness of the programmers just
look for the http:// prefix... the start of an URL cant be the
continuation of another (in many cases... not all eg. if you pass
another url to a CGI as an argument to the CGI call)
If you don't really need to join files well you don't need to add
spaces of course...
Anyway I suppose the random char is not a valid url char. If the
random char was a valid url char nobody could understand where
the URL finishes (with as usual exception... maybe it is a sort of
DB file, or Pascal String where the first ASCII code before the URL
string is its lenght)
