Ik ben een beetje aan't prullen in PHP.
Nu zit ik met het probleem dat bepaalde pagina's, telkens als ze geladen 
worden, er anders moeten uitzien.
Echter, als de URL niet verandert, haalt de browser die pagina graag uit de 
cache. En dus: de pagina verandert *niet*.

Hoe kan ik de browser nu dwingen om de pagina *toch* te herladen?

Een snelle Google bracht me bij:
http://vancouver-webpages.com/META/metatags.detail.html

# The date and time after which the document should be considered expired. 
# Controls cacheing in HTTP/1.0. In Netscape Navigator, a request for a
# document whose expires time has passed will generate a new network 
# request (possibly with If-Modified-Since). An illegal Expires date, e.g.
# "0", is interpreted as "now". Setting Expires to 0 may thus be used to
# force a modification check at each visit. 

Mijn vraag: is (voor wat ik wil doen) dit een goeie oplossing:

<META HTTP-EQUIV="expires" CONTENT="0">

Of kan ik beter iets anders proberen?

alvast bedankt
flo
