Probleme mit dem Cache

Postby gbg » 08. February 2007 15:48

Hallo allerseits,

ich bin leicht am verzweifeln, aber wahrscheinlich einfach nur zu dusselig.
Wir haben auf einem W2k3 Server den Apache installiert.

Die normale Website besteht aus "statischen" Seiten und Grafiken. Dynamische Anteile werden durch Abfrage eines "eigenen" Servers per XMLHttpRequest vom Client abgerufen und dort per JavaScript ausgewertet.

Soweit die Einleitung.

Solange ich kein Caching anschalte läuft alles stabil und Prima auch dauerhaft. Sobald ich das mod_cache.so in Betrieb nehme läuft der Apache einige zeit normal, nach einiger zeit allerdings bekomme ich im error.log lauter FILE NOT FOUND Meldungen und es werden konsequent keine Dateien mehr an die Clients gesendet .

Hier mal unsere httpd.conf (Kommentarzeilen sind gekürzt)
Code: Select all

Was ich erreichen möchte ist es das die "statischen" Seiten gecached werden um möglichst schnell an die Clients geliefert zu werden.

Bin für jeden Hinweis auf das Problem dankbar.
