using this control works fine for smaller files, but barfs with anything
large. i haven't pared it down to find the threshold where it succeeds or
fails, but i know it works for a file of around 2MB, but fails for a file of
around 10MB.

(i know HTTP POST isn't the optimal way for large file upload, but for our
needs right now it's what we can use.)

i've uploaded a 24MB file on x-drive.com using HTTP POST, so i'm pretty sure
it's not a limitation of the protocol.

thanks,
Kirk

This is what Scott Guthrie had replied to a similar question on ASPLists
before ..

"A customer on the listserv had mentioned in Beta1 that hackers were
attempting denial of service attacks on his site by trying to
deliberately upload huge files (100s of Mb -- and then relying on user
code to incorrectly handle these large sizes). As such, for Beta2 we
added the ability to configure a maximum request size limit on file
uploaded content. By default it is 4 MB.

If you want to make it higher you can do some by editing either your
machine.config or your application's local web.config file and setting
the "maxRequestLength" attribute on the httpRuntime section handler (the
value is the number of KBytes to support -- so 8000 would be around Mb).

<configuration>

<system.web>

<httpRuntime maxRequestLength&#"8;000"/>

</system.web>

</configuration>

Hope this helps,

Scott

P.S. Note that it looks like there might have been a bug in Beta2 that
limited the max size of supported file uploads to something between
24-30 Mb (as such, if you are trying to upload a 100Mb file with Beta2
you might have problems). This was fixed for RTM."
