HTTP POST via NDIS IM

NTDEV
1

Hello, Guyz.

I’m writing a driver and need it to send a HTTP POST QUERY to a web
server at NDIS IM level.

Can you please give me some links on the stuff that I can use for
that, maybe some examples etc.

Any information greatly welcomes.

Thanks alot.

I suggest that you consider creating a usermode service to interact with
your driver (via IOCTL, inverted call model, etc.) and issue the HTTP
request from usermode. You will find that to be significantly easier than
trying to do it from kernel mode.

Much has been said about the various ways a usermode service can enhance a
kernel mode driver. Search this NG for “Inverted Call” or look at the
various resources available on www.microsoft.com/whdc for starters.

Once you get your head around having a usermode service do some work for a
kernel mode driver, consider using the system supplied WinHTTP object to
manage the remaining details of sending a POST and processing the result (or
such things as proxy, redirect, etc.)

Good Luck,

Offhand, I’d say you have picked the wrong tool for the job.

NDIS IM drivers are designed to operate below the protocol stack (TCP/IP in
your case), and it’s hard to break that model. Use a usermode helper
application.

Writing a helper user app or service is a good idea.
