Squid retry_on_error: amakhodi wesimo nemizila ehlukile
Sebenzisa i-Squid retry_on_error ngaphakathi kobubanzi besimo esibhaliwe kanye nendawo ehlukile, esikhundleni sokuyithatha njengesethingi esijwayelekile sokuphinda izicelo.
Kukhona ukukhetha ku-Squid okubizwa nge-retry_on_error, kodwa igama likhulu kunencazelo yalo ewusizo. Akusho ukuthi isicelo ngasinye esihlulekile sizophindwa ngokungenamkhawulo kuze kusebenze ikhasi.
Ezinguqulweni ezisekela lo myalelo, ukucishiwe ngokuzenzakalela. Uhlu lokuphinda olubhaliwe luthi 403, 500, 501, 502, 503 kanye no-504, futhi isicelo sizanywa ngendawo enye esebenzayo. Lokhu kubaluleke kakhulu ohlelweni olunezindlela ezinye zokudlulisa. Akukhona nje ukuphinda okulindelwe kwesikhathi kwesokhethi efanayo iye kuseva efanayo.
Qala uqambe ukwehluleka
Ukwenqatshwa ngesikhathi kuxhunywa ku-proxy, ukwehluleka kokuqinisekisa i-proxy, iphutha le-HTTP elivela emthonjeni, kanye nempendulo enqanyulwe ngemuva kokuqala kokulethwa akunikezi ithuba elifanayo lokuphinda. Ungalindeli ukuthi isethingi eyodwa izophatha konke lokhu kune ngendlela efanayo.
Ngokuphuma okuyimfihlo, nquma futhi ukuthi indlela ehlukile iyamukeleka yini. Omunye umzali angaba nekheli lomthombo womphakathi elihlukile, inqubomgomo yokuqinisekisa, noma indawo yenethiwekhi. Ukuphumelela ngaleyo ndlela ehlukile kungase kwephule isizathu sokukhetha umzali wokuqala.
Imisebenzi yohlelo lokusebenza iletha okunye ukukhathazeka: ukuphinda isicelo kungaphinda umphumela waso. Iklayenti neseva zidinga incazelo efanele yokuphinda, ikakhulukazi emisebenzini edala noma eshintsha idatha. Isethingi se-proxy asithathi indawo yokuphatha imiphumela engaqinisekile ezingeni lohlelo lokusebenza.
Funda umyalelo wenguqulo yakho ngqo; inkomba ibala ukutholakala nokuziphatha okuzenzakalelayo. Gcina futhi izikhathi zokugcina zesicelo kanye nesikhathi sokulinda esibonwa umsebenzisi engqondweni. Umzamo owengeziwe wokudlulisa ungase usebenzise isikhathi esisele ngaphandle kokuletha umphumela ongcono.
Lapho uphenya ukwehluleka okwenzeka ngezikhathi ezithile, rekhoda isimo, umzali noma indawo ekhethiwe, kanye nokulandelana kwemizamo. Uma kungenjalo, ukuphinda kungase kwenze inkinga yomzila ephindaphindayo ibonakale njengewebhusayithi enenswelu ngokujwayelekile kuyilapho ifihla indlela ehlulekile ngempela.
