HTTP request : login.

Hello, I'm currently writing a mini-browser (with C++) I've made sockets, connexion on an HTTP server, and I manage to get the pages with the "GET" method, get the header, and the datas. I manage to download any type of files (easy : just to copy data after header into a binary file, and I write a JPG, or a ZIP...) I have to interpret HTML code, but it is not a problem My problem is about cookies and logins : For exemple : if I want to check my mails, I "get" the login page : I detect the "

code, find variables to fill and send, but how do I send it ? with the "POST"'s HTTP functionnality ? I may receive a cookie, how do I get it ? Do I need to read it ? Or do I just post the login datas, and the server allows me to connect ? I tried to "GET" the link I have once logged, but it send me back a page with code "302 FOUND" (or 203), with the redirection of Login page : sure ! But if I post once the datas about login, will a request like GET on the previous link won't give me the "302 FOUND" anymore ? thx !
