Expiration and the Expires Header
It is highly recommended that all Web servers use a scheme for the expiration of all Web pages. It is bad practice for a Web server not to supply expiration information via the HTTP Expires response header for every resource returned to requesting clients. Most browsers and intermediate proxies today respect this expiration information and use it to increase the efficiency of communications over the network.
One way we can control the cache by adding meta tags :
META HTTP-EQUIV="Pragma" CONTENT="no-cache"
META HTTP-EQUIV="Expires" CONTENT="-1"
Or By PHP Scripts :
header("Cache-Control: max-age=300, must-revalidate");
header("Pragma: no-cache");
header("Cache: no-cahce");
Header("Cache-control: private, no-cache");
Header("Expires: Mon, 26 Jun 1997 05:00:00 GMT");
Header("Pragma: no-cache");
Additional to that you can add
header ("Last-Modified: " . gmdate ("D, d M Y H:i:s") . " GMT"); advance cash loan payday quickcash instant loan payday till,payday loan or cash advance savings account,cash loan paydaycash loan payday tilcash advance new yorkadvance cash loan online paydaylawsuit settlement cash advance,advance cash lawsuit loan,lawsuit cash advancefirst american cash advance5 advance cash illinois loan,cash advance loan illinoisquick cash payday loanadvance cash faxing no,no faxing savings account cash advance,1000 advance cash faxing nopayday loan cash advance loancash loan payday tilladvance cash loan payday softwareadvance america cash advance,advance america cash first,advance advance america cash centermississippi online cash advance,cash advance online no faxing,online cash advancecash loan payday untilfree on line casinofree internet casinoonline roulette gambling,roulette online,roulette game free onlineblack jack,play black jack online free,computer black jackcasino secure online gamblinginternet video pokerblackjack bettingfree online roulette,play roulette online free,roulette game free onlinemultistrike video pokerblack jack gamblingcasino slots on line,casino on line,line casinobest casino gamble internet online,casino gamble,online casino gambleno deposit casino codevirtual casino gamblinggambling casino online bonushow to win at blackjackbest casino bonusonline blackjack game,free blackjack game download,blackjack gametriple play video pokeronline backgammon game,backgammon game,free online backgammon gameonline casino reviewcasino cash,free casino cash no deposit,free casino cash bonusfree no download video pokerbest video pokerbest internet casinouk online casino,uk casino gambling online,online casino in the ukfree blackjack casino game,free blackjack game download,free blackjack gamelearn to play blackjack free,blackjack game free ware,free blackjackdueces wild video pokercasino video pokerplay blackjackonline card game casinointernet slotsfree online casino,free online casino no download,free sign up bonus at online casino
