Imodi ye-proxy ye-HTTP ye-Ncat ngokumelene ne-TCP relay egxilile

I-byte relay egxilile ishiya ukucutshungulwa kwe-HTTP ku-proxy ekhona. Imodi yokulalela i-HTTP ye-Ncat iyisevisi ehlukile eqonda iphrothokholi.

client → local TCP relay → existing forward proxy → destination

Kulolu hlelo, i-relay inendlela eyodwa ephezulu egxilile. Idlulisela isicelo somklami ngaphandle koshintsho ku-proxy yaphambili ekhona. Leyo proxy ifunda i-URL ephelele noma i-CONNECT target, isebenzisa inqubomgomo futhi ivule uxhumano lwendawo ekuyiwa kuyo.

Ukuqondisa i-relay ngqo kuwebhusayithi kushintsha isivumelwano. I-proxy yaphambili kufanele ikhethe izindawo zokuya futhi ibhekane nokwakheka kwe-HTTP nokuziphatha koxhumano; ukukhipha igama lomsingathi emgqeni wokuqala akwanele.

I-Ncat ye-Nmap inikeza ngokwehlukile imodi yokulalela eqonda i-HTTP:

ncat --listen 127.0.0.1 3128 --proxy-type http

Lesi sibonelo se-loopback sisebenzisa ukuqaliswa kwe-proxy kwe-Ncat, hhayi isici esabelwana yiwo wonke nc. I-proxy yayo ohlangothini lokulalela ibhekana nezindlela ze-HTTP ne-CONNECT. Izinketho zayo ze-SOCKS ohlangothini lomklami azimisi iseva ye-SOCKS kumodi yokulalela. Isevisi ehlanganyelwe ehlala njalo nayo idinga ukuphathwa koxhumano ngamabomu, ukulawulwa kokufinyelela nokuloga.

Ukuze ubuke, thola umngcele wokubethela. I-relay kuxhumano lwe-proxy ye-HTTP oluvamile ingabona izicelo nezimpendulo ze-proxy. Ngemva kwe-CONNECT, i-HTTPS yendawo ekuyiwa kuyo ingamabhayithi e-TLS, hhayi okuqukethwe kwekhasi okufundekayo. I-TLS eya ku-proxy ifihla ngisho nokushintshana kokuqala kwe-proxy kulolo xhumano. Sebenzisa ukuxilonga komklami ne-proxy emisebenzini echazwe, futhi uvikele amalogi angaba nezifakazelo noma ama-URL abucayi.
