How to get a session value from browser (FF/IE)

[sadjoker]

Hello.
I wrote an application for data mining from a website with login/password.
I managed to extract the info from the website but every time i have to login manually from the browser, get the PHPSESSID from the browser`s cookies info manually and put it into the application so it has access to the inner website content. Or if i use IE, i have an addon to show the headers and get the cookie info from there. Is there any way to get automatically this PHPSESSID from the browser (Firefox or InternetExplorer)?
I tried checking the cookies.txt for Firefox but there is no info for PHPSESSID, only the other cookies. Or can i get the PHPSESSID with the program and launch the browser with the same PHPSESSID so i can be logged in with bot: the program and the browser? Or maybe i have to read browser`s memory? Or spy on the http traffic and analyze http headers and get the cookies value from the headers?
I`m thinking about that for 2 days now and can`t get a right solution. Is there any easy way to do it? Thank you.

You must only read the incomming header and resend Session as cookie..

resend CookieList

void AppendHeader( const QString nam , const QString val )
{
   /*  QHttpRequestHeader header;
 */
    ///////////std::cout << "### Send cookie ->" <<  qPrintable(val) << std::endl;
   header.setValue(nam,val); 
}

void AppendHeader( const QString nam , const QString val )
{
   /*  QHttpRequestHeader header;
 */
    ///////////std::cout << "### Send cookie ->" <<  qPrintable(val) << std::endl;
   header.setValue(nam,val); 
}

IMO: is not code from shool ... but its run..

Yes, i know how to extract the cookie from the header and sent it again, but only my program will have the session and browse the website. What i want is... my program to have the session AND my browser to have the session. So while my program searches the page, i can browse with Firefox and watch the other things. Do you have solution for that?

[sadjoker]

I think i got a solution. I compiled a simple console proxy server transparently forwarding all the http requests and i`ll try to run it with QProcess and read the http headers from the output. The browser proxy settings, i`ll try to set automatically from my program.

Also, i found that Firefox keeps the session ID into sessions.js in the profile`s folder.
But i can`t find where IE keeps it...
