Controlling page flow

Question

I would like to change the content of the url the moment the surfer arrives on a new page, in other words, when the surfer presses the 'reload' button the app will update this page, not execute the previous post again.

One Answer, No Delphi Required

(~match|(~litPosted~)=yes|(~page|targetPageID~)~)
(~set|litPosted=yes~)
(~webActionPostData.execute~)
(~page|targetPageID~)

Better Answer, Requires Delphi

This not ideal because the page will be generated twice, but it does work.

In Delphi:

StringVar['AfterBounce'] := 'Yes';
Response.Send( MacroStart + 'Bounce|MyPage' + MacroEnd);

In a WHTEKO file:

// the following is within the page named MyPage
<head>
(~MATCH|(~AfterBounce~)~Yes|(~chMetaStaticRefresh~)~)
(~SET|AfterBounce=No~)
</head>

<whdroplet name="chMetaStaticRefresh">
<META http-equiv="Refresh" content="0; URL=(~ACTION|(~PageID~)~)">
</whdroplet>
