I have two pages in an iframe. One is running a pretty intensive update process. I check the server using the top command in linux, and generally it is taking 28-40% of my CPU time, split between httpd and mysqld. I don't know if that's good or bad by the way.
the other page in the iframe is reading a file written by the first page, and it refreshes by javascript every 15 seconds to update on the status of the first process.
This all only works in theory - when the update process is running, the second file just hangs, I get the blue progress bar and "waiting" at the bottom of the browser, but the file doesn't come up.
I'm only putting this in the database forum because I'm wondering if mysql's settings have anything to do with this. I have found from experience that if I call a page that talks to a database, closing the browser window doesn't stop the process on the server; I check with top and that process is still running till it's done.
Any help would be appreciated on this, I need to know why I can't call one page when another is running - that seems pretty miserable.
Thanks,
Sam
