TRIM Url

lets say I have a URL in a string like "http://www.blabla.com/adf/adf/asdf/asdf/asdf/asdf.asp"

how can I "trim" everything before the 3rd slash?

Edit: I'm using ASP w/ vbscript

Figured it out:

VB Code:

dbErrFileSlash = Instr(1, dbErrFile, ".com") + 3                    'find character position after .com
        dbErrFile = right ( dbErrFile, (len(dbErrfile) - dbErrFileSlash))   'cut everything before the first /
