Re: [PHP] Browser cache setting
All the browsers cache unless the end user works at it to change that, or you force it to not cache by giving it a different URL each time. Playing games with no-cache headers (et al) will only give you a bug-list of arcane browwses that don't honor those headers.

Re: [PHP] Browser cache
I think the right answer (at least the right for me) is adding a rand value to the link of the image, that makes the browser load it every time. Thanks a lot for your help!. Best Regards.

No this is the first if statement but there are nested if's after that.
I'd post the code but everyone yells at me about my coding style. If you
promise not to yell I will post it.

I just looked at my hosting service thinkg it may have been because
they just upgraded to 4.1 php. so I dumped my database and loaded it
to my machine at home and find that it does the same thing.
I have 4.06 php on win me my hosting service is 4.1 php on redhat
linux
so
I'm thinking that is not the case.
I have used this code through out my site and this is the only part
it
does
this on and I am not understanding why.

My officemate and I talked about this and the only thing he could
come
up
with was a possible problem with your parser. Are you using a
beta
version
or something unusual? I don't know if you have a way to know this
-
the
programmers didn't set up PHP where I work, but I know our web
server
is
apache and it's on a unix box. I've never run into this problem
before.
Have you had it happen in other programs? Have you ever used this
code
in
another program? If it's consistently incorrect then it may be a
problem
with your parser. That's not really my area of expertise, but
it's something you could look into if no one else has any better
ideas :-)

Does it show the message and the form or just the message?

Subject: Re: [PHP] If else question
If and else expect to be followed by exactly 1 statement. To
aggregate multiple statements as one, surround them with
{curly braces}. I'm guessing you didn't do that, and you're
seeing the execution of all but the first of the statements
following the
else.
So it should be:
if ($var1)
echo can't be found;
else
{
echo first line of form;
echo second line of form;
}
This is what I have:
if($quantity 1)
{
echo Sorry I can't seem to locate this item;
}
else
{
do this
}
So yes I have done exactly as you have stated and it still shows
the form.

I can see that IE5 does not cache the page locally, by looking in Temporary Internet Files. I realize now though, that what I really need is to drop certain pages out of the browser "back" chain. For instance say I have three pages: A -- B -- C Once the user selects page C, I don't want them to see page B with the browser back button. If they use the back button, I want them to jump from C all the way back to A. IOW, I want to "unlink" B from the chain. Is that possible?
