Hi,
I need a code to do that:
Log in a site that uses post to receive username and password.
Then I need to save a html file from that site. The site uses sessions to identify if I'm logged or not, then it only allow-me to download the html files if I've logged and continues using the same session id.
in other words, i need to login in login.php, then get the file xxx.php saving it to my HD.
Thanks ind advance.

Ah, ok, this can be done in 2 ways: or the site store a cookie with your session id in your browser, or the site use a GET parameter to propagate the session ID in the urls.
You must identificate the session mechanism. If the session is stored in a cookie, you can add a TCookieManager to the TIdHTTP component to store the cooki, if the mechanism is via ssid propagation inthe url... you must get the ssid parameter and append it to the url for make the download.
The coommon situation is to use a ssid propagation via URL in the first page viewed, and once login, store the session id in a cookie in the browser.
I don't help you more without know the site...
hmm, no code solution, but a simple download cmdline tool: WGET (http://xoomer.virgilio.it
with this, call it twice like this:
wget --save-cookies=cook.txt --post-data="Name=MyUserNa
wget --load-cookies=cook.txt "http://www.thesite.com/se
the tool can save/load cookies/sessions, supports ssl, ftp/http, recursive download (yes - a website backup), listfiles, proxy support and and and... to make it short: i guess youre faster done with this way

You can use the Indy library of internet VCL components.
If your Delphi does not have them, you can download it from its homepage: http://www.indyproject.org
Then you can use a TidHTTP client component for make the post of the login form
Here you have an example of Put with parameters:
procedure TForm1.Button1Click(Sender
var
Parameters: TIdMultiPartFormDataStream
begin
Parameters := TIdMultiPartFormDataStream
try
//Add the used parameters for the script
//See all the parameters used in your case!
//including hide parameters...
Parameters.AddFormField('u
Parameters.AddFormField('p
//Call the Post method of TIdHTTP and read the result into TMemo
Memo1.Lines.Text := IdHTTP1.Post('http:/www.Ex
finally
Parameters.Free;
end;
end;
Later, in the Memo1 you have the result of the form send.
Instead of a Tmemo, you can save it in a file.
You must provide to the script the required parameters present in the html page that contains the form.
