Convert a BinaryRead to ASCII Characters (need speed)

[wanttoscript]

I am improvising a "file upload" in VBScript, and have succeeded, except in the matter of performance!

I need to convert the binary data returned by the BinaryRead method to ASCII, and do it like this:

postData = ""
Dim biData
biData = Request.BinaryRead(Request.TotalBytes)
for nIndex = 1 to LenB( biData)
postData = postData & Chr(AscB(MidB( biData, Index, 1)))
next

Unfortunately this is very slow for files >100K.
Does anyone have a nifty idea for doing this quicker?

All advice will be most graciously accepted.

I found something that speeds things up a little (but not as much as advertized) ...
