+ \brief qxtweb application core class. communicates, delegates, does all of the magic ;)
+
+
+ QxtWebCore is the base class of your web application.
+ it listens to the scgi protocoll
+
+ construct one webcore object in the main function of your application.
+ you must contruct it AFTER QCoreApplication and BEFORe any controllers.
+
+ \code
+ int main(int argc,char ** argv)
+ {
+ QCoreApplication app(argc,argv);
+ QxtWebCore core();
+ core.listen(8080);
+ QxtWebController controller("root");
+ app.exec();
+ }
+ \endcode

+
+/*!
+ \fn static QxtWebCore* instance();
+ singleton accessor
+ \fn static void send(QByteArray);
+ Send data to the client. Use this rarely, but use it always when sending binary data such as images. \n
+ normal text/html comunication should be done using the controllers echo() function \n
+ note that after you called send the first time you cannot modify the header anymore \n
+ sending may be ignored by the transport when there is no client currently handled
+ \fn static QIODevice * socket();
+ direct access to a iodevice for writing binary data. \n
+ You shouldn't use that unless it's absolutly nessesary
+ \fn static QxtError parseString(QByteArray str, post_t & POST);
+ much like phps parse_string \n
+ \fn static QByteArray readContent(int maxsize=5000);
+ reads the content from the current socket if any has sent. \n
+ returns an empty QByteArray on any error. \n
+ the content is cut at maxsize and not read from the socket. \n
+ FIXME:\warning: this function is BLOCKING. while content is read from the client, no other requests can be handled.
+ FIXME:\warning: due to paranoid timeouts this might not work for slow clients
