only-if-cached wuxuu proxy-ga ka codsanayaa jawaab la kaydiyay

Ka codso HTTP cache iskaashi jawaab hore u jirtay oo 504 u fasir sidii ku guuldareysi cache ah, ma aha xakamayn bixitaan heer shabakadeed.

Codsi ku habboon inuu isticmaalo jawaab hore loo kaydiyay, HTTP waxay qeexdaa Cache-Control: only-if-cached.

Macmiilku wuxuu ku diri karaa proxy-ga kaydinta HTTP:

curl --proxy http://127.0.0.1:3128 \
  --header 'Cache-Control: only-if-cached' \
  --include http://www.example.org/report

Cache ixtiraamaya amarkan waa inuu soo celiyaa jawaab la kaydiyay oo waafaqsan xannibaadaha kale ee codsiga, ama 504 Gateway Timeout marka uusan buuxin karin codsiga. Halkan 504 wuxuu muujin karaa siyaasadda cache halkii uu ahaan lahaa xiriir TCP fashilmay oo proxy-ga ah.

Amarku si otomaatig ah uma oggolaado nuxur duugoobay. Cusbaanta, shuruudaha xaqiijinta iyo beeraha Vary ee waafaqsan wali way muhiim yihiin. Amarka codsiga no-cache wuxuu beddelkeeda dalban karaa xaqiijin guul leh isha ka hor inta aan dib loo isticmaalin.

Tani waxay sidoo kale ka duwan tahay dejinta habka xaqiijinta offline ee cache. only-if-cached waxaa lagu qaadaa codsiga shaqsiga ah wuxuuna muujinayaa waxa macmiilku diyaar u yahay inuu qaato.

Isticmaal cache taageera habdhaqanka. Amarka codsiga la iska indhatiray ma aha firewall, markaa ka-hortagga adag ee taraafikada kor u kaca wuxuu u baahan yahay siyaasad shabakadeed ama server si madaxbannaan loo dhaqangeliyay.

Proxy HTTPS CONNECT caadi ah ma arko madaxyada HTTP ee sirta ah mana hayo walxaha bogga tunnelkaas. Tusaalahu wuxuu si ula kac ah u isticmaalaa kheyraad HTTP fudud oo cache-ku processing karo.
