c# - How to clear browser cache on browser back button click in MVC4? -


i know popular question in stackoverflow. have gone through every same question , unable find right answer me. log out controller action result

    [authorize]            public actionresult logout(user filtercontext)     {         session.clear();         session.abandon();         session.removeall();         response.cache.setcacheability(httpcacheability.nocache);         response.cache.setexpires(datetime.utcnow.addhours(-1));         response.cache.setnostore();         formsauthentication.signout();         return redirecttoaction("home", true);      }

it didn't work me. tried adding-

<meta http-equiv="cache-control" content="no-cache" /> <meta http-equiv="pragma" content="no-cache"/> <meta http-equiv="expires" content="0"/>

none of these resolved issue.

the problem approach setting late mvc apply it. following 3 lines of code should put in method shows view (consequently page) not want show.

response.cache.setcacheability(httpcacheability.nocache); response.cache.setexpires(datetime.utcnow.addhours(-1)); response.cache.setnostore();

if want apply "no cache on browser back" behavior on pages should put in global.asax.

protected void application_beginrequest() {     response.cache.setcacheability(httpcacheability.nocache);     response.cache.setexpires(datetime.utcnow.addhours(-1));     response.cache.setnostore(); }

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
