c# - Starting a new thread on a web page button click -

-

i have inherited legacy app , there code can simplified down to:

protected void somebutton_click(object sender, eventargs e) {     var otherthread = new system.threading.thread(delegate()     {         system.threading.thread.sleep(20000);         fireanasyncprocess();     });     otherthread.start();      thankyoupanel.visible = true;     otherpanel.visible = false; }

the fireanasyncprocess() seems intermittently failing run. of course number of things wondered:
given pause of 20000 above, fireanasyncprocess() called after button click has been handled? new thread called regardless of happens thread called it?

edit: result/outcome of fireanasyncprocess() not required on web page , page not intending wait them. rather trying start thread , assume gets fired.

this web environment - each request handled in own thread context, , thread.start() isn't useful: child thread aborted after request been handled, , parent thread aborted.

so if need run piece of work on button_click, should host wcf service or windows service or being able accept message web-application , run job in background.

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
