Ok, I can see why it is 'Generally' frowned upon.

However I have a page that needs to refresh the contents of an iframe once every minute and I can think of no simpler way of doing it.

It can disorient the users[^] or break the functionality of the "Back" button of the browser[^]. See the Wikipedia article[^].

Good links, thanks.

But I have a page that shows the league tables as they stand, so it needs to be refreshed every minute so that it is bang up to date, and the meta refresh is how I do it.

If it is bad practice, how else would I do this?

A JavaScript setTimeout call that refreshes the page after 1 minute?

Fair enough, it has the same functionality, but it is not as simple though is it. Smile | :)

This should do the trick.

XML

<html>
<head>
<script type="text/JavaScript">
<!--
function setRefresh(timeoutPeriod) {
    setTimeout("location.reload(true);",timeoutPeriod);
}
//   -->
</script>
</head>
<body onload="JavaScript:setRefresh(60000);">
</body>
</html>

I know how to do it, my point being it is much simpler with a simple meta call.

you do it with AJAX. you make Javascript xhttp calls to your server to get the updated sections of your page (either HTML itself or the raw data which you then format with Javascript on the client).

the page itself never refreshes, but its content does.

It is not really a programming question, merely wondering why a certain function is regarded as bad.

You can use jquery to call a webservice via ajax, and paint the

container with fresh data every minute using a jquery or javascript timer.

When the new data is received, parsed and html is built, just do a update to the container in 1 line of code. If the data doesn't change, abort the update.

Proxy Server Proxy-Connection and Connection headers question.

Hi everyone.

I'm writing some kind of transparent proxy server in C#.
The code works without any problem and does what it have to do, but I am really confused about the Connection and Proxy-Connection headers in requests!
As everyone knows, the Proxy-Connection is not an standard header and only signals the proxy server to keep the connection open and so,
I remove this header form the request
and forward the request after removal, but here is an unclear role form W3:

HTTP/1.1 proxies MUST parse the Connection header field before a message is forwarded and, for each connection-token in this field, remove any header field(s) from the message with the same name as the connection-token.

As W3 does not count the Proxy-Connection in the standard headers and suggests to use the Connection header instead, should I remove that header form the request before I forward it or not?
Right now I am doing it but I want to make sure if I must or must not do it. Smile | :)

No one?!

Well, the last post I made in the PHP forum now appears in here http://www.codeproject.com/Forums/1213650/Linux-Apache-Perl-Python.aspx[^]

And CSS forum looks to be merged with this very forum.

Looks like mine have mostly been moved to Linux, Apache, Perl, Python (Forum)....

If they are gonna merge the forums, least they could do is add a ", PHP too! oh my!", to it.
