URL & Parameters (POST)  from IWebBrowser2 current page

Hi there,

I'm looking for a way to query IWebBrowser2 for the current page displayed in it, including any POST parameters that were sent to it.
I've tried using BeforeNavigate2 event and keeping track of the history myself, but it's called for every frame in the page, and if I'm redirected to the same page, it's called, but the browser doesn't add it to its history, and then I lose sync with the back/forward buttons.
Another problem is when the user presses 'backspace' to go back, no event is connected to it.
Access to the history associated with the WebBrowser would have solved it, but seems like there's not such a thing.

Thank you,

Yudi.

I'm not sure I understand your question.  POST data is sent from the browser BACK TO the server, not the other way around.

Oh, sorry, I mean every POST data that were sent to the server before the server returned the page.

What does it mean to be "Always On"?

Hi Migel, thanks for remembering :)
Well, after some experiments, I got to the conclusion that it's not enough.
I'm trying to keep my history synchronized with the back/forward buttons, so I can know the POST data that was sent to the server for every page I got till now.
It's getting more complicated when I have more than one frame. And there are some more problems too.
The WebBrowser sometimes add the new page to the history and sometimes not (for examle, when the user clicks a link that brings him to the same page), and then my 'back/forward' buttons go out of sync.
Right now I'm working on a more complicated history tracking, but I think it might be an overkill, cause I know the WebBrowser maintains its own history, including the POST data that was sent for every page.
Sorry for the long story :) Anyway, I need something that will give me the ability to resend the request programatically for a certain page the user has been to, and I need it to work for 99% of the pages.

Hi!
you can enum all frames in the current document and catch event in the any frame you want.
IMHO you need to store brief description of the document (at least frames that it hold) and check requests from the frame (store not only post data but document URL and frame that make web request)

Well, that's what I'm trying to do now, get the URL, post data, and every URL and post data for every frame in the current page and store it in my history, but it's a bit wierd that you cannot simply access the history information from the WebBrowser...
