You can do that by using any good HTTP client component. There are a few on the market and at least two good which are free: Indy and ICS. ICS is freeware with full source code. It is included by Borland on Delphi 7,8,2005 and 2006 partner CD/DVD. You can download also from http://www.overbyte.be. See HttpTst demo included with ICS. Shortly, using the HTTP client component, you specify an URL and call one of the HTTP methods such as GET or POST. Then the component grab the answer from the server and present it to you. You can then examine it and issue more requests. Along with a HTML rendiring component and a scripting engine, a HTTP client component is the base of any internet browser application. Sending data to a webserver is not more complex: basically you format a stream (TFileStream, TMemoryStream or any other) with the data in the format the webserver expect (url-encoded, form data, mime,...) and issue a POST method for the given "action" URL. You don't even need to "get" the form page if you know what data fields, which action and which encoding there is. Also, don't forget the cookies: frequently you have to get some page or to post some data (login form) just to receive a cookie from the server. Then you must provide the cookie value for each subsequent request. The cookie is somewhat your authentication token. Some pages are protected by usercode/password. ICS HTTP client will handle that for you using "basic authentication" or "NTLM authentication". Just feed the properties with the require values. Some pages are "relocated". That is the server reply something like "sorry, the page you requested is there". ICS HTTP component will take care of that for you. Finally, at some places, network access is going thru a proxy or firewall. The ICS HTTP client component will also handle that for you if you specify the proxy parameters (type, port, address, credentilas,...). -- Contribute to the SSL Effort.
