javascript - Restrict user to go BACK after Payment has been done -


i have integrated payment gateway in web application made in mvc4 razor. after payment has been done user redirected return url..

then process generating unique id ,sending payment details sms blah blah..

[nocache] public actionresult ipgresponse()         {             //send sms..             //save payment response..etc              return redirecttoaction("thankyouuploaddocument");         }

then redirect action.

public actionresult thankyouuploaddocument()         {             //do              return view("thankyouuploaddocument" , paymentviewmodel);         }

the problem when user hit .it goes ipgresponse() , steps again .

i have used [nocache]..but did not worked

i have restrict user go ipgresponse() or payment gateway again..

this should prevent caching:

        httpcontext.response.cache.setexpires(datetime.utcnow.adddays(-1));         httpcontext.response.cache.setvaliduntilexpires(false);         httpcontext.response.cache.setrevalidation(httpcacherevalidation.allcaches);         httpcontext.response.cache.setcacheability(httpcacheability.nocache);         httpcontext.response.cache.setnostore();

and idea server-check when form gets submitted , return error in case dark magic cache works. shouldn't.

edit: prevent browser's 'back' button loading cached page, question about. of course need check on page-enter see if transaction has taken place.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
