Izimpendulo ze-Squid 403: ukwenqatshwa okusha noma iphutha eligciniwe?
Ihlukanise ukwenqatshwa kokungena okusha nempendulo engemihle egciniwe ngaphambi kokushintsha inqubomgomo yesikhathi sokuphila se-cache ye-Squid.
Ukubona ikhasi 403 elifanayo kabili akubona ubufakazi bokushaywa kwe-cache. Qhathanisa irekhodi lokungena lomsebenzi kanye nezihloko zempendulo nemibuzo emibili: ngubani odale ukwenqatshwa, futhi ingabe impendulo egciniwe isetshenziswe futhi?
- Isicelo esenqatshwe endaweni sidinga ukuthi isinqumo somthetho wokungena noma ubunikazi baso silungiswe.
- Ukwenqatshwa okusha okuvela kumthombo kusho ukuthi umthombo usenqaba isicelo.
- Impendulo yomthombo esetshenziswe futhi idinga ukuthi inqubomgomo yayo yobusha nokucushwa kwe-cache okusebenzayo kuhlolwe.
I-cache ye-HTTP ihlanganisa izimpendulo ezingezinhle ezithile ngaphansi kwemibandela yayo, kodwa i-403 ayitholi ubusha be-heuristic ngokuzenzakalelayo. Ukwenqatshwa okungenzeka kugcinwe kungase kuthwale isikhathi esicacile se-cache ehlanganyelwe. Ukushintsha imvume kumthombo akukusuli impendulo esabhekwa njenge entsha; sebenzisa inqubomgomo yempendulo efanele ezinqumweni okungafanele zigcinwe.
I-negative_ttl ye-Squid iyindlela yokubuyisela ehlukile yezicelo ezithile ezehlulekile ezinokuphela okungaziwa. Inani layo elizenzakalelayo elibhaliwe liwuziro ezinguqulweni ezihlanganiswa yireferensi yomyalelo wamanje. Lokhu akuvimbeli izimpendulo zamaphutha ezenziwe zaba ntsha yimiyalelo ecacile ye-HTTP.
Ireferensi idinga futhi ukwakhiwa okuvumela ukwephulwa kwe-HTTP futhi akufaki i-Squid 8. Ungadlulisi isiphakamiso sesikhathi sokuphila se-Squid 2.7 kokunye ukukhishwa ngaphandle kokuhlola ukusekelwa. Ukususa into kungase kususe uphawu olusheshayo; inqubomgomo eyenza ukuthi isetshenziswe futhi iyona enquma isicelo esilandelayo.
