Queries to server during longpolling

Question

I make longpolling query to, say, http://polling.site.com/polling . At the same time I need to make several other queries to server, say http://site.com/polling/?d=cr . But they are quenued and are fineshed only when longpolling connection finishes. Picture related

I use nginx/apache2, php5.

How can I make several queries during longpolling?

Answer 1

The reason was in the inability to use php session in two connections. So I used session_write_close in longpolling loop and at this time second query completes.
