How to change url parameter between link click and page display

markdj

I have a web page where clicking a link sends you to www.foo.com/bar.php?id=0. I then compute a new id in bar.php and subsequent link clicks show the new id value in the browser url address bar (www.foo.com/bar.php?id=1234). However, it stays with id=0 for the initial call up after login. Since I will have computed a new id prior to sending http data from server to client, how can I get the parameter changed in the url so that the first page display shows the computed parameter value instead of the initial parameter value?

In other words click on www.foo.com/bar.php?id=0 endup with www.foo.com/bar.php?id=1234 displayed in browser url address bar,where "1234" varies.

Use this as a template, Change
<Seconds> to 1 or 3 (enough time to read the redirection message)
<URL> Page that you are sending them to.

<!DOCTYPE HTML>

<meta charset="UTF-8">
<meta http-equiv="refresh" content="<Seconds>; url=<URL>">

<script>
  window.location.href = "<URL>"
</script>

<title>Page Redirection</title>

<!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->
If you are not redirected automatically, follow the <a href='http://example.com'>link to example</a>
