 |
|
Hi there guys,
How in my application do i intercept HTTP Post operations being done
in Internet Explorer or other browser...So when user submits a form
with a number of fields, i can get the submitted values and pass it further?
Should i hook Winsock send/recv or there is more high-level API to hook on?
Code samples would be greatly appreciated.
Thanx alot,
Eugene.

You can use an NDIS device driver that hooks the WinSock stack directly. If
you do not want to write your own device driver from scratch (which you
cannot do with Borland's tools anyway - you need Microsoft's DDK for that),
then look at using a third-party driver, such as WinPCap
([url]http://www.winpcap.org)[/url].

That, on the other hand, is a very different issue. In the case of IE
specifically, there are ways you can hook the browser window directly via
its own DOM interfaces without using a device driver at all. This does not
work for any other browser. Refer to MSDN for more details, or search at
http://www.deja.com for earlier posts on this issue.
