Domain Routing Logic<\/h1>\n\n\n\n

Excerpt:<\/strong>
Domain routing logic odre\u0111uje kako domeni, subdomeni, DNS zapisi, web serveri, reverse proxy i aplikacije zajedno odlu\u010duju gde \u0107e korisni\u010dki zahtev zavr\u0161iti.<\/p>\n\n\n\n

Domain Routing Logic<\/h2>\n\n\n\n

Domain routing logic je osnova svakog stabilnog web sistema. Kada korisnik otvori domen, zahtev prolazi kroz vi\u0161e slojeva: DNS, eventualni CDN\/proxy servis, web server, reverse proxy, aplikacioni server i samu aplikaciju. Ako bilo koji sloj nije uskla\u0111en, sajt mo\u017ee raditi delimi\u010dno, pogre\u0161no ili uop\u0161te ne raditi.<\/p>\n\n\n\n

Prvi sloj je DNS. Domen mora pokazivati na pravi server ili servis. A zapis vodi domen na IP adresu, CNAME obi\u010dno vodi subdomen na drugi hostname, dok MX zapisi upravljaju email saobra\u0107ajem. Gre\u0161ke u DNS-u \u010desto izgledaju kao server problem, iako zahtev nikada ne sti\u017ee do pravog mesta.<\/p>\n\n\n\n

Subdomeni su va\u017ean deo routing logike. Glavni sajt mo\u017ee biti na osnovnom domenu, API na api<\/code> subdomenu, automation sistem na posebnom subdomenu, a blog u folderu ili na zasebnom subdomenu. Svaka od tih odluka uti\u010de na odr\u017eavanje, SSL, SEO i infrastrukturu.<\/p>\n\n\n\n

Kada DNS dovede zahtev do servera, web server ili reverse proxy odlu\u010duje \u0161ta dalje. Apache, Nginx ili Caddy proveravaju hostname, putanju, SSL stanje i pravila rutiranja. Na osnovu toga zahtev mo\u017ee oti\u0107i ka stati\u010dkom HTML sajtu, WordPress instalaciji, Docker container-u, Node.js aplikaciji ili internom API-ju.<\/p>\n\n\n\n

Folder routing i subdomain routing ne re\u0161avaju isti problem. \/blog\/<\/code> struktura je dobra kada sadr\u017eaj treba da ostane jasno povezan sa glavnim domenom, dok je subdomen koristan za odvojene aplikacije, interne alate ili servise koji imaju druga\u010diju tehni\u010dku logiku.<\/p>\n\n\n\n

Clean URL pravila tako\u0111e pripadaju domain routing logici. Sakrivanje .html<\/code> ekstenzije, redirect sa stare na novu adresu, canonical URL i interna mapa ka stvarnim fajlovima moraju biti precizno pode\u0161eni. Lo\u0161e rewrite pravilo mo\u017ee lako poremetiti WordPress, API endpoint-e ili stati\u010dke fajlove.<\/p>\n\n\n\n

Kod vi\u0161e sistema na istom domenu treba pa\u017eljivo praviti izuzetke. Na primer, ako root HTML sajt koristi posebna .htaccess<\/code> pravila, WordPress u \/blog\/<\/code> folderu mora biti izuzet iz tih pravila. U suprotnom, admin, permalinks, REST API ili builder funkcije mogu prestati da rade.<\/p>\n\n\n\n

SSL routing mora pratiti domensku strukturu. Svaki domen i subdomen koji prima HTTPS saobra\u0107aj mora imati odgovaraju\u0107i sertifikat i jasnu redirect logiku. Ako se me\u0161aju www<\/code>, non-www<\/code>, HTTP i HTTPS varijante bez plana, brzo nastaje konfuzija.<\/p>\n\n\n\n

Domain routing logic je va\u017ean i za SEO. Pretra\u017eiva\u010di treba da vide jednu jasnu verziju svake stranice. Ako isti sadr\u017eaj postoji kroz vi\u0161e URL varijanti, bez canonical pravila ili redirect-a, autoritet se razvodnjava i struktura sajta postaje nejasna.<\/p>\n\n\n\n

Dobra domain routing logic omogu\u0107ava da korisnik, browser, server i pretra\u017eiva\u010d uvek zavr\u0161e na pravom mestu. Kada su DNS, SSL, rewrite pravila, reverse proxy, folderi, subdomeni i aplikacije pravilno povezani, web sistem deluje jednostavno spolja, iako iza njega mo\u017ee stajati kompleksna infrastruktura.<\/p>\n","protected":false},"excerpt":{"rendered":"
