Question about cache of Ajax request results of IE

Source (detailed): http://www.cnblogs.com/artech/archive/2013/01/03/cache-4-ie.html

Solution 1: solve the problem by adding a suffix to the URL address

  <!  Doctype html  >   <  Html  >       <  Head  >                      <  Script  Type  = "Text/JavaScript"  > $ (  Function  () {Window. setinterval (  Function  () {$. Ajax ({URL:  '  @ URL. Action ("getcurrenttime ")?  '  +   New Date (). totimestring (), success:  Function  (Result) {$ (  "  Ul  "  ). Append (  "  <Li>  "   + Result  +   "  </LI>  "  );}});},  5000  );});  </  Script  >         </ Head  >    </  Html  > 

Solution 2: solve the problem through Ajax settings of jquery

 <!  Doctype html  >      <  Html  >          <  Head  >                      <  Script  Type = "Text/JavaScript"  >  $ (  Function  () {$. Ajaxsetup ({cache:  False  }); Window. setinterval (  Function  () {$. Ajax ({URL:  ' @ URL. Action ("getcurrenttime ")  '  , Success:  Function  (Result) {$ (  "  Ul  "  ). Append (  "  <Li> "   +  Result  +   "  </LI>  "  );}});},  5000  );});  </ Script  >         </  Head  >     </  Html  > 

Solution 3: Use MVC to solve problems through custom response

  Public   Class  Homecontroller: controller {  Public  Actionresult index (){  Return View ();} [nocache]  Public   String  Getcurrenttime (){  Return  Datetime. Now. tolongtimestring ();}}  Public   Class  Nocacheattribute: filterattribute, iactionfilter {  Public   Void Onactionexecuted (actionexecutedcontext filtercontext) {filtercontext. httpcontext. response. cache. setcacheability (httpcacheability. nocache );}  Public   Void  Onactionexecuting (actionexecutingcontext filtercontext ){}}
