I need some help with Win32/Apache/PHP/MSSQL concurrency. I'll consider contract help if necessary (please quote your rates if this is an area you have experience in):
I have two php scripts A and B, being executed in different browser windows;
Script A makes a php system() call to launch a C++ executable that takes about 30 seconds to execute;
Script B makes several (quick) php mssql_query() calls;
Both scripts work fine independently, but script A seems to "block" script B until script A completes;
By "block" I mean the browser window in which it runs does not render, and the animation icon indicates the page is loading -- until script A completes, then the page load completes immediately.
TIA,
ed
