.net - Session Variable Mismatch Between Postback -


i'm storing session variable use pass parameter various data access calls. variable set when session first created, , can changed user depending on resources have access to. instance, when user first logs in default session value might set "1". in top corner of page dropdownlist of options have access , changing changes session variable... 1, 2, 3, 4... etc.

the problem session variable may change between postbacks due 1 of following reasons:

  1. session timeout, causes session recreate default value of 1
  2. user opens 2 tabs/browser windows , changes on 1 tab, switches other page rendered using "1" value

this causes controls on page become "stale" , postbacks don't behave correctly. button click event relied on session variable in event handler may not "intended" event, , interface misleading.

what i'd able determine if session variable's value has changed between postbacks, , if has redirect same page causing re-render using new session variable value, , giving user clear indication each postback does.

any ideas?

why don't use cookie instead store variable? think both of problems addressed that.

php newbie here, struggling crazy head around how go implementing http_referer-based security feature woefully inept downloads system. basically, have file download pages have specific string appended end of url, specific string being: ?thanks if visible in url, users able download file situated on it. works great, it's easy 'unlock' page adding '?thanks' part onto url themselves. allowing users bypass clumsy security , access premium files ease. if possible, i'd add security measure whereby attempting access page containing string '?thanks' did not arrive page containing '?pending' redirected homepage. make perfect solution me. just clarity, typical pre-download process goes this: user visits download page: [website]/download/page/123/ user completes recaptcha, gets redirected here: [website]/download/page/123/?pending user fills in details, gets redirected here: [website]/download/page/123/?thanks user receives file long-...
