Hoi,
Ik heb een virtual server waarop OpenSuse draait. Opzich draait het wel redelijk (voor die prijs dan). Ik heb echter 1 probleem.
Bij het posten van een form (php) wordt na het posten een redirect uitgevoerd. Dit blijft af en toe heel erg lang hangen (zodat mensen vaker op de submit button gaan klikken). Na een seconde of 30 gaat het script toch verder. Dit is echter soms het geval en niet altijd (ik denk wanneer er meerdere mensen op de site zijn)
Nu heb ik in het bestand /etc/apache2/server-tuning.conf
wat veranderd bij het aantal connecties maar dat lijkt nog steeds geen oplossing te bieden. Iemand enig idee?
