I want to make behave slightly different the first time you load it to
when it refreshes itself - it auto refreshes using a meta refresh tag.

Is there anyway to do this WITHOUT cookies and/or Javascript?

If the page is "page.php" you can make the refresh link be something
like "page.php?refreshed=1". Would that do what you want?

But then it is going to refresh itself with the same parameters isn't it?


I don't think short of javascript as a replacement for
<meta http-equiv="refresh" content="107" />

or whatever, there is any way to do this.

No it's going to refresh itself with an additional parameter which can be
handled with a php

if refresh{...

surely?

The first time that script is executed then refresh is FALSE

or am I missing something?

Yes, that seems to meet the specification you gave, but if you want the
behaviour to be different every time, you can generate a different
number for 'refreshed' every time. This is, after all, a server-
generated page.

Maybe I am misunderstanding what the "this" is.

I assume that the OP is not aware that the content attribute optionally
accepts a URI, e.g.:

<meta http-equiv="refresh" content="5; url=http://example.com/">

However, I'd rather avoid http-equiv=refresh at all.

More specifically, if the OP's page is

http://example.com/mypage.php

then he can code

<meta http-equiv="refresh" content="5; url=http://example.com/mypage.php?refreshed=1" />

and the php can then determine whether the meta refresh invoked the page or
not, by testing if it passed the "refreshed" option in the GET.

Note that this does not help distinguish initial page loads from page loads
initiated by the browser's "Refresh" option (^R or equivalent).

The code mentioned on stackoverflow.com seems more promissing:

Which all appear to involve a Javascript solution.

The OP asked for a solution that worked "WITHOUT cookies and/or Javascript".
