URL shortening
billion times.other uses url shortening beautify link track clicks disguise underlying address.although disguising underlying address may desired legitimate business personal reasons open abuse.url shortening service providers found spam blocklists use redirect services sites trying bypass blocklists.websites prevent short redirected urls posted.in addition service delivery time increases length url also increase.example page history page generated url httpsen.wikipedia.orgwindex.phptitleurlshorteningactionhistory shortened httpsw.wikiozb.
URL shortening
purposes several reasons use url shortening.often regular unshortened links may aesthetically unpleasing.many web developers pass descriptive attributes url represent data hierarchies command structures transaction paths session information.result urls hundreds characters long contain complex character patterns.urls difficult memorize type distribute.
URL shortening
result long urls must copied pasted reliability.thus short urls may convenient websites hard copy publications e.g.printed magazine book latter often requiring long strings broken multiple lines case email software internet forums truncated.on twitter instant messaging services limit number characters message carry – however twitter shortens links automatically using url shortening service t.co need use separate url shortening service shorten urls tweet.services using url shortener allow linking web pages would otherwise violate constraint.shortening services goo.gl tinyurl.com bit.ly generate urls humanreadable although resulting strings longer generated lengthoptimized service.
URL shortening
finally url shortening sites provide detailed information clicks link receives simpler setting equally powerful serverside analytics engine unlike latter require access server.urls encoded two dimensional barcodes qr code often shortened url shortener order reduce printed area code allow printing lower density order improve scanning reliability.registering short url websites create short links make sharing links via instant messaging easier make cheaper send via sms.done online web pages url shortening service batch demand may require use api.a wellknown websites set url shortening services use – example twitter t.co google g.co godaddy x.co.techniques url shortening every long url associated unique key part toplevel domain name.example httpstinyurl.commqxt key mqxt.
URL shortening
redirection treated equally redirection instruction sent browser contain header http status moved permanently found temporary redirect permanent redirect.there several techniques implement url shortening.keys generated base assuming letters numbers.case character sequence ... b c ... z. alternatively uppercase lowercase letters differentiated character represent single digit within number base .order form key hash function made random number generated key sequence predictable.users may propose custom keys.
