[SOLVED] Do dynamic responses (PHP, Django, etc) set any sort "not static" variable in the response header?

Do dynamic responses (PHP, Django, etc) set any sort "not static" variable in the response header?

If I have some site on a server:

//hello.html
<html> hello </html>

Would all of the following be requested and/or cached individually:

http://hello.html, http://hello.html?place=world, http://hello.html?foo=bar

...even though they are the same result?

Is there some variable in the header that denotes the difference between a static (always the same) response to a request and one which has had some meddling (ie. PHP, templates)?

EDIT: if the site was (I don't know PHP):

<html><?php
   print "hello"+$_GET['place'];;
?></html>

the results would be different for the three urls:

http://hello.html, http://hello.html?place=world, http://hello.html?foo=bar

Is the response header also changed to express that for all three the page is not static (not cacheable)?

Solution

This answer is based off of a comment by @CharlotteDunois. If he adds an answer, I'll take this one down.

There is no implicit difference between the header of a dynamic vs static response.

There does exist a header setting called Cache-Control which can tell a browser that something that does not look static actually is.

If doing I'm the one doing the web service, I can set the header to have Cache-Control, but I can not depend on other servers to always do the same.
