Submit an ASP Web Page and Collect Results

[Johnnie Norsworthy]

I need to be able to programmatically connect to an ASP base web site,
populate some fields and capture the resulting web page. Is there any
helpful information around to get me started in Delphi. I do not need the
web page to ever be displayed, just merely captured as a series of strings
or as a text file.

Can someone nudge me in the right direction for this? My web/newsgroup
searches didn't.

If you use Indy, play with the TidHTTPClient - what you want to do is
basically send the data to the remote site - you do this by simply calling
say the POST function of the TidHTTPClient ... the data you can either send
from a pre-loaded stream, or from a HTML file u already have on disk.

After downloading and installing "Proxomitron" I found a better tool to find
the Headers and PostData. I modified the WebBrows example provided with
Delphi to tell me the Header and PostData using the
WebBrowserBeforeNavigate2() event.

Now I have a good idea of the actual data being sent during a post. There's
quite a bit to decipher, but I'm getting closer.

For example: From the WebBrows program I determine:
Content-Type: Content-Type: application/x-www-form-urlencoded
and
PostData=sql=%28FIELD2+Like+%27A%25%27+%29&FIELD1=&FIELD2=A&FIELD3=&FIELD4=&
FIELD5=&FIELD6=
(ignore line wrap)

How should this data be fed to the Indy HTTP Client and posted? I'm sure I
need to translate something in the postdata. I am using the HTTP CLient
Demo to test my tries.

Also, since I expect to return a large amount of data, should I stream
directly to disk?

If, in the web form the "submit" is in the form:
<FORM name=Form action=search/search1.asp method=post> ...
should the URL I use be the relative one presented in the action= field?

I know after I get one of these "posts" working the rest are going to drop
like dominos.

Thanks for any help,
Johnnie

The following code loads the data to post from a stream, then sends that
stream to the URL (cbURL.text).
The "Response" variable is getting back whatever reponse the remote http
server sends back.

Source := TMemoryStream.Create;
try
Source.LoadFromFile(edPostFile.Text);
HTTP.Post(cbURL.Text, Source, Response);
finally
Source.Free;

HTH.
