Izikhathi zempilo ze-HAProxy ze-Squid proxy edlulisayo
Yakha isikhathi sempilo se-HAProxy esikhuluma ne-proxy edlulisayo futhi uhlukanise ukufinyeleleka kwesilaleli, ukwamukelwa kwe-CONNECT nokutholwa okuvela emsukeni.
Ifayela elibizwa nge-/check.txt kusihambisi se-proxy lizwakala njengomgomo ocacile wempilo. Inkinga ukuthi isilaleli esidlulisayo esicacile se-Squid akusona isizindalwazi esijwayelekile esihlinzeka ngomsuka wamadokhumenti alowo msingathi.
Isicelo sesitayela somsuka esifana ne-HEAD /check.txt HTTP/1.1 siyeka umgomo ophelele olindelekile wesicelo se-HTTP esijwayelekile esidlula ku-proxy edlulisayo. Kuye ngokuhlelwa, singase senqatshwe noma siphathwe enye insizakalo yendawo. Yomibili imiphumela ingase isho okuncane kunalokho okushiwo idashibhodi.
Khetha insizakalo okufanele uyigcine itholakala
| Ukuhlola | Ubufakazi obusizayo |
|---|---|
| Ukuxhumana kwe-TCP nesilaleli se-proxy | Inqubo efinyelelekayo iyakwamukela lokho kuxhumana. |
| CONNECT emgomweni olawulwayo | I-proxy iyakwamukela leso sicelo somhubhe. |
| Ukuthola i-HTTP nge-proxy | Indlela yesicelo ekhethiwe ingabuyisela impendulo elindelekile. |
Esimeni sesithathu isicelo sidinga umgomo, isibonelo:
HEAD http://probe.example.internal/proxy-ready HTTP/1.1
Host: probe.example.internalIgama lomsingathi liyisibonelo kuphela. Sebenzisa indawo yokugcina elawulwayo i-proxy engayixazulula futhi evunyelwe ngamabomu ukufinyelela kuyo. I-http-check send ye-HAProxy isekela ukukhetha indlela, i-URI, inguqulo namakhanda; hlela leso sicelo ngokusobala esikhundleni sokuthola ifa lesibonelo seseva yomsuka singashintshiwe.
I-HEAD ingahlola isimo sempendulo namakhanda. Ayikwazi ukuqinisekisa umzimba wempendulo ongalokothi udluliswe. Uma isivumelwano sempilo sidinga uphawu emzimbeni, khetha ukuhlola kwe-GET okufanele futhi uqinisekise lolo phawu.
Gcina i-akhawunti yokuhlola nemikhawulo yomthombo incane lapho kukhona ukuqinisekiswa kwe-proxy. Ukukhulula isilaleli sonke ekuqinisekisweni ukuze uthole uphawu oluluhlaza kushintsha insizakalo evikelayo.
Ekugcineni, nquma ukuthi ukuhlola okwehlulekile kufanele kususe ini. Ukuphazamiseka komsuka olawulwayo kungase kwenza ukuhlola kokudlulisa kwayo yonke i-proxy kwehluleke ngesikhathi esisodwa. Lokho kungase kube ukuncika ofuna ukukukala, noma isizathu sokugcina impilo yesilaleli nokutholakala kusukela ekugcineni kuya ekugcineni njengezimpawu ezihlukene.
