Here is how I handle events: Objective, to download several files, very similar to the Httpasy demo: On GoButton.Click: HttpCli.GetASync OnHeaderEnd: Check if the file to be downloaded is good. If not, ABORT. OnRequestDone: If ABORT, then clear the file, if not store the downloaded file. Then get the next file. The problem is that IF the statuscode is 302 and I Abort, then I cannot get the next file because the component is busy. (httpDNSLookup). I have solved this problem by having the first line in OnRequestDone check the status, and only execute the routine if it is httpReady. (i.e. Procedure OnRequestDone begin if httpcli.state = httpReady then begin the rest of the OnRequestDone code; end; end; ) My question is: Is there a bug in the component, or is there a better method of doing this? - Original Message - From: "Francois PIETTE" <[EMAIL PROTECTED]> To: "ICS support mailing" Sent: Sunday, February 26, 2006 6:21 AM Subject: Re: [twsocket] HttpCli problem >> Thank you for the feedback, Francois and Wilfried.

Re: [twsocket] HttpCli problem
Thank you for the feedback, Francois and Wilfried. I have not been clear in my explination. Let me start again with more detail: State: httpReady I call httpcli.GetASync. State: httpDnsLookup ( on HeaderEnd) State: httpWaitingHeader StatusCode: 302 I call httpcli.About State: httpReady (OnRequestDone) State: httpDNSLookup Nothing is done between OnHeaderEnd and OnRequestDone, so I assume that httpcli is looking for the redirect. (This only happens with a 302 StatusCode, with a 200 Statuscode, OnRequestDone state is httpReady). If this is a 'Feature' and not a bug, then can I Abort again in the OnRequestDone? Or what do you recommend? I do not think that the second DNSLookup will provide me with any useful information, even if it is a redirect, I wouldn't know how to use it, so I might as well cancel it and try to get the next file. - Original Message - From: "Francois PIETTE" <[EMAIL PROTECTED]> To: "ICS support mailing" Sent: Saturday, February 25, 2006 1:12 PM Subject: Re: [twsocket] HttpCli problem >>> Why use a loop ? >>> Why don't you want to use OnRequestDone event ? > >> That is the problem.

Re: [twsocket] HttpCli problem
That is the problem. This routine is called from OnRequestDone. That is why
I think that there is a bug. OnRequestDone gets called twice for 302s, but
I have already taken that into account.
Should httpcli.State = httpReady when OnRequestDone is called? If so, this
is not the case with 302.

Re: [twsocket] HttpCli problem
I did find a work-around, but it is not pretty:
while httpcli.State <> httpready do
begin
a:=a+1;
log.Lines.add('Waiting '+inttostr(a));
application.ProcessMessages;
end;
This is only needed after a 302. The counter ranges from 400-1000 before
the state turns to httpready. And I am not sure that they are real 302s.
The same pages give a statuscode of 302 consistently when downloaded in the
same order, but may give a 200 if downloaded in a different order. Could a
bug in my program make httpcli give a fake 302 statuscode?
(The above code gives an infinite loop if application.processmessages is
removed)

Re: [twsocket] HttpCli problem
The problem is that the STATE is not ready after the abort, so when I use httpcli to grab another file after a 302, I would get an error. (http component busy, I think). After an abort in such a case, is there anything that I have to do to make sure that the component is ready for the next use?

Re: [twsocket] Off Topic ICS and MidWare Frappr group
ICS is 'PostCardWare' in part because the author enjoys seeing where his users are. Frappr is the coolest thing since post cards. Therefore, we were emailed for something important, and well worthwhile. Also, I would suggest increasing the price of ICS to a postcard AND a Frappr pin. Since we are off-topic, if V7 does not support D7, then I will have to spend hundreds of dollars upgrading Delphi. I will not have problems doing that. This shows that ICS is worth quite a bit to me, and I think that it would be a good idea if there was a PayPal site for ICS contributions. (Amazon Europe Gift Cards are too complicated for me...) Yes, I did contribute to keep this list going. ( http://www.elists.org/donate/ ) (So I don't start a flame war, I understand the masses that hate to be emailed or have their email address compromised. Changing your email address because you cannot access it anymore due to the thousands of daily junk emails is not a pleasant experience.

The OnHeaderEnd routine gets called twice when using passwords, the first time with a negative contentlength, the second time with the proper value. Using D7, httpprot 1.83. (It only gets called once when not using usernames/passwords, which is what it is supposed to do) - Ronny that's the usual way http works. When you cal for a URL with a user/password within an authentication, you have the following steps : The request is sent once, without authentication. you then get back a 401 error. The httpCli component then analyses the authentication method (and realm) and then sends back a request with the user/password encoded in the authentication header. so you have th OnHeaderEnd trigger twice because of the first 401 answer and then with the "correct" answer. [note] although i don't know why there *must* be a first 401 when you provide username/password, i suppose it's a way to know the exact authentication method...
