HttpWebRequest Class Annoyances

[Threads]

Hi,

Anyone out there familiar with the old WinInet routines for httpsendrequest and httpopenrequest and such? Although it wasnt as easy to work with as HttpWebRequest, it did have features that seem to be missing in HttpWebRequest. For example, the whole cookie thing... by default the WinInet libraries would get the current cookie for the domain you were requesting the page for from IE, and put it in the headers, that way sites that a user was logged into that I was interacting with, automatically found the login information. With the HttpWebRequest, that is completely lacking... now that said, I know it is possible to add a cookie manually to the header, but they dont even give a way to look up the default cookie that the current user has for it. I am stuck using the old InternetGetCookie WinInet function to do that. Plus, since it doesnt automatically get the cookie, it doesnt automatically update the users cookie if a change is made.

By default, all the cookie operations were happening in WinInet so that it would get the current cookie, and change the current cookie in the browser if a change was detected. This behavior could be turned off obviously, but it was very helpful.

It seems to me that with HttpWebRequest, there is not even a setting for this behavior to continue. Furthermore, it doesnt offer the functions necessary to get the current cookie (must revert back to using InternetGetCookie in WinInet). Am I wrong about this? Is there some hidden setting that I am not seeing that I can change to make it do what WinInet use to do?

I know it sounds like Im just complaining a lot, but one of the problems I have run into is that even when I set the cookie manually, then make a request, if the request is redirected (you can set the max number of redirects) it doesnt use the cookie I set for it to use when it is redirected, so it is like the user is not logged in again. The problem is that a lot of the pages have automatic redirects when you are submitting data to a form and such, so suddenly the response I get back doesnt even have the user logged in anymore.

Sorry for rambling If you made it this far you deserve some milk with those cookies.

Im not sure I understan what youre trying to do with all that rambling...

The HttpWebRequest has a CookieContainer property that lets
you retrieve the cookies associated with the request. The
HttpWebResponse has a Cookies collection which does the same
thing, only for the web response.

You could also use the requests
Headers collection and find the get-cookie one (or whatever the
response cookie header is called). To set a cookie, just send a
response in a HttpWebResponses Headers collection, with
Set-Cookie and the cookie values.

Does that help?

I know it can be done using that, but the problem is that I need to get the users existing cookie that they have in IE using the InternetGetCookie in order to add it to the HttpWebRequest.

Also, even if I have a cookie in the HttpWebRequest, if it is redirected by the server, the cookie doesnt get sent to the page it is redirected to.

Also, since I have to manually get the cookie, then add it to the CookieContainer, when I receive each response, I need to use InternetSetCookie (wininet) to set the IE cookie so it is updated in case the user wants to go to the site manually in a browser.

Are you familiar with working with cookies and sites that require cookie authentication using WinInet?

Im afraid I dont know how to go about this, sorry. I was hoping it
was something simple that I mentioned that would help.

Maybe someone else can pick this up...

Pain in the ***

I got the same problem. Im trying to write a little web spider that would get the odds from www.betbase.info.
Page uses cookie to let you in, so i need to use it the same way that browsers do.
I can access first page, but when i try to go anywhere else, i get redirection exception (infinite loop).
If I find anything else about this Ill let you know
