Nambari ya hali ya HTTP itakuambia haraka na kwa urahisi hali ya wavuti uliyopewa. URL nzuri na inayofaa inapaswa kurudi na majibu ya 200 kuonyesha ombi la mafanikio limetolewa.
Mbali na 200, nambari zingine kadhaa za hali ya kawaida ni pamoja na:
200- Ombi limefanikiwa
301- Rasilimali iliyoombwa imepewa URI mpya ya kudumu na marejeo yoyote ya baadaye ya rasilimali hii INATAKIWA kutumia moja ya URI zilizorejeshwa.
302- Rasilimali iliyoombwa inakaa kwa muda chini ya URI tofauti.
401- Ombi linahitaji uthibitishaji wa mtumiaji.
404- Haipatikani, seva yake haijapata kitu kinacholingana na Ombi-URI.
500- Hitilafu ya Seva ya ndani
503- Huduma haipatikani, seva yake sasa haiwezi kushughulikia ombi kwa sababu ya kupakia kupita kiasi au matengenezo ya seva.
