VB Forum / Controls / December 2004Inet1 - getting URL after redirection
The Inet1 (Internet Transfer Protocol) control automatically handles a server redirection (eg 302 object moved generated from, say an ASP response.redirect) -- ie if you connect to a site and the server redirects you to another site, Inet1 automatically retrieves data from the site to which you are redirected. This is great. However, how can you get the URL of the site you have been redirected to? The problem is that the Inet properties (RemoteHost, URL...) are NOT updated to reflect the URL of the page you end up on. They continue to show the original URL, which is of zero use, as you already know this. Knowing the new URL is essential if subsequent posts etc. need to use the new URL (which might even be a different domain). The information also does not appear in the response Headers. The new URL DOES appear as the "Location" header in the original 302 response from the server, but I can't see any way of getting hold of this. ie this is the problem. Trapping the StateChanged event does not seem to offer a solution. No matter which State you trap you can't get at the new URL. I've tried using the handle from the Inet1 hInternet property with the Wininet API InternetQueryOption but the handle is always invalid. I can't find any documentation on whether this is meant to work or not so trying it was just an unsucesseful stab in the dark. This is a really simple requirement. Surely there is a way to tell what URL you have connected to using the Inet1 control. If so, what is it?

Your answer was completely irrlevant. I went to a lot of trouble carefully describing my problem with the Inet1 control. Why then post me a link about redirection with the Winsock Control. It has no bearing on the problem at all. My original question shows clearly I understand redirection. I'm trying to get some information from the Inet1 control, not to find out what redirection is or what the Windsoc control can do. I don't want to be rude but clogging up the news groups with completely irrelevant responses helps nobody. > Handling HTTP redirection: > http://www.vbip.com/winsock/winsock_http_07_01.asp [quoted text clipped - 33 lines] > URL >> you have connected to using the Inet1 control.

If so, what is it? You again miss the point. There IS NO HEADER RESPONSE provided by Intet1 that you can use. That's the point of my question. Have you used the Inet1 control to discover the URL you have been diverted to? If not, no point in responsing is there? If you HAVE used it to do this, then prove that you understand the question by explaining how to discover where you have been diverted to. Your response so far provides no useful information. Please read my question carefully before responding. >>> The new URL DOES appear as the >>> "Location" header in the original 302 response from the server, but I [quoted text clipped - 62 lines] >> > URL >> >> you have connected to using the Inet1 control.

You said it yourself, in your first message. The Inet control _automatically_ handles redirection. Have you considered the possibility that you *can't* get what you now want, by using that control? I'm not saying that's necessarily the case, but if it does turn out to be, then Veign's suggestion is nowhere near "irrelevant" Meanwhile, you may want to consider what effect your apparent attitude is having on other people who might have been interested in helping you. I've never used the Inet control, preferring instead the Winsock, but I may have been interested enough to investigate, to assist someone asking similar questions. Not in this case, though. Bob Yes, it is indeed possible that the Inet1 control will not provide the results. But it just might as it's a common requirement. I am trying to find out if it will. To simply move directly to talking about other technology with no reference at all to the technology (eg Inet1) is not helpful. It's like if you were to ask a question specifically about Win 98 and the answer comes back about win xp with no reference to the original Win98 problem. I know you haven't used Inet1 (so once again, not sure why you responded) but moving from Inet1 to Winsoc for the things one uses Inet1 for is a major undertaking. Once again, it would be like you saying you have a formatting problem in Microsoft Word and somebody comes back and suggests using C++ to process your document. Not helpful. Neither were Veign's two responses. And clogging up these newsgroups with off the cuff, irrelevant suggestions is a major problem. It makes finidng information difficult. Silence is usually a far better response. >> You again miss the point. There IS NO HEADER RESPONSE provided by Intet1 >> that you can use. That's the point of my question.

I have used the Inet control but will pass on putting anymore time into this thread. Good luck in your search for the answer...

Trouble is the method you describe can't be used to get header information if you have read the data using the Inet1 control. So I think you are wise to pass on putting anymore time into this as you clearly don't understand the issue. > You stated that the header contained the information you were interested > in [quoted text clipped - 95 lines] >> >> > URL >> >> >> you have connected to using the Inet1 control.
