forcing a page refresh?

ronjon

heres my deal.

im building an image gallery.... i have a page(index.php) that has a list of events....when a user clicks an event.... it loads a new separate page (viewpicsframeset.php) with the pictures from the event. the page uses information such as filename and location i send via url to decide which pictures to show.

its also worth mentioning that the gallery is date driven... when the date changes... it shows a different set of events that they can choose to view.

heres my problem.

when the user closes the viewpicsframeset.php.... and the date changes..... when they click on a new event...and the viewpicsframeset.php loads back up.... it shows the previous set of pictures from the previously viewed event... not the newly chosen event....

worth noting #2... if i click refresh... it shows the correct pictures...

so... i guess what i need help on is... if you guys can tell me the code to force a page refresh when a page is loaded up... or if you guys know a more efficient and cleaner way of resolving this issue...

thanks a bunch in advance guys...

one thing i figure could be a good solution was to have the page not cache. i looked it up.... the 'pragma' 'no-cache' thing.... i tried it... but i couldnt get it to work...

worth noting

the viewpicsframeset.php is a frameset of two pages... the one on the left is picslist...where the user can choose any thumb to click on....and when they do click... it loads the picture on the right frame.... the target.php frame.

when i tried the pragma no cache thing... i put it on the meta tags on all pages.... target.php, picslist.php, and the main frameset - viewpicsframeset.php.

but for some reason it still keeps caching the pages.

heres one deal that might be causing the problem...
i have a bootscript on viewpicsframeset.php that boots the user if theyre not authenticated... so i had to put the meta tag below some php tags... i dunno if this makes the no cache thing not work...

can you guys help me out?

thanks again...
