Umbuzo we-WHOIS ngaphakathi komhubhe we-HTTP CONNECT
Landela ukuxhawulana kwe-proxy kanye nesicelo se-WHOIS njengokuhwebelana okubili okuhlukene lapho umzila we-HTTP CONNECT ovunyelwe uthwala umbuzo we-TCP ku-port 43.
Uma uphenyo oludingekayo lusasebenzisa i-WHOIS yendabuko, i-proxy ye-HTTP ingathwala lokho kuhwebelana kwe-TCP uma inqubomgomo yayo ivumela i-CONNECT enkonzweni ye-WHOIS. Iklayenti kufanele iqedele ukuxhawulana kwe-proxy ngaphambi kokuthumela umbhalo wophenyo. Okokuhlolwa kwe-WHOIS komphakathi okuvunyelwe ngaphandle kwezicelo zokungena ze-proxy ezilungisiwe, uhlu lwama-proxy e-HTTP lunikeza abalamuli abangabameleli; qinisekisa ngokwahlukile ukuthi eyodwa ivumela umsingathi wensizakalo ye-WHOIS kanye ne-port 43.
Kunsizakalo yokucabanga ebizwa nge-whois.example, qala ngalesi sicelo se-HTTP:
CONNECT whois.example:43 HTTP/1.1
Host: whois.example:43
Bhala iziphetho zemigqa ye-HTTP njenge-CRLF. Funda impendulo ephelele ye-proxy, kuhlanganise nomugqa wokhanda ongenalutho oyiphethela, bese uhlola isimo sempumelelo esiyinombolo. Ukwamukela ingxenye yomugqa wesimo akwanele ukuqala iphrothokholi elandelayo.
Bese uthumela umbhalo we-WHOIS
Ngemva kokuba umhubhe uvulekile, thumela umbuzo olindelwa yileyo sevitha ye-WHOIS. Umbuzo oyisibonelo olula uthi:
example.com<CRLF>Lesi simakadi simelela amabhayithi okubuyiswa kwengola nokudluliswa komugqa. Akusona ingxenye yegama lesizinda. Akukho mugqa we-HTTP GET noma isimo sempendulo ye-HTTP ngaphakathi kwalokhu kuhwebelana kwe-WHOIS.
Funda umbhalo kuze kube yilapho isevitha ye-WHOIS ivala uxhumano. Impendulo ingaqukatha imigqa eminingi; umugqa omusha wokuqala awusho ukuthi isiphelele. Gcina izikhathi zokulinda zoxhumano nokufunda zilinganiselwe ekusetshenzisweni.
Lokhu kulandelana kunikeza umhlaziyi imingcele emibili ehlukene. Kuqala kuza ibhloko lamakhanda e-HTTP. Ngemva kwalokho kuza impendulo ye-WHOIS, okuqedwa kwayo kuboniswa ukuvalwa koxhumano. Gcina noma imuphi umbhayithi ogcinwe kubhafa ngale komngcele ohlaziyiwe esikhundleni sokulahla ukufunda konke kwenethiwekhi.
Ukwenqatshwa yi-proxy kusho ukuthi umhubhe awuzange uvuleke, ngakho ukuthumela isizinda ngemva kwalokho akukwazi ukukhiqiza umphumela we-WHOIS. Uma impendulo yesevitha ikhomba kwenye insizakalo ye-WHOIS, noma umbuzo olandelayo udinga uxhumano lwawo oluvunyelwe kuleyo nsizakalo.
