For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Using the header function

Posted by ukgeoff (geoff), 15 April 2005
The following code does different things depending on the browser.

     header ("location: test");
  header ("Refresh: 2; URL=");

In Firefox: Email client is activated and browser redirects to page.

In Opera: Email client is activated and browser stays on current page.

In IE: Email client is activated and browser has blank page. Actually it has the php page but of course there is nothing to see.

What do I need to do to get a consistent response?

To me, those look like conflicting headers ... which is, I think, why it's inconsistant.  To get it to behave consistantly, have it do one thing or the other ... not both.  

Posted by ukgeoff (geoff), 18 April 2005
Both are acceptable headers in their own right.

The question has to be; how do you send two headers from the same script and have them treated as if they were nothing to do with each other?

I.e., in pseudo code

Here's header one
I'm finished
Here's header two

Posted by admin (Graham Ellis), 18 April 2005
No ... I mean are you allowed to send out a refresh along with a location?  Aren't they mutally exclusive?   I've on an "icky" connection and away from teh revelevant books so may be talking through my hat ....
