When using a session together with an internal link, say :

                  <a href="#bottom">go to bottom</a>


the resulting url is say :

                  http://www.tre.dds/programs/?session_id=3l344l4j3l#bottom

which directs to :
 http://www.tre.dds/programs
instead of say                http://www.tre.dds/programs/mypage.php#bottom

URL's matching "^#" should be left alone by the transparent session-id-adder, since they are internal to that page.

Workaround: Write href="/programs/mypage.php#bottom"

The workaround
  href="/programs/mypage.php#bottom"
does not work, for 
  session_id=?
is inserted between mypage.php and #bottom

This works :
  <script language="JavaScript">
    var str1="<a hr";
    var str2="ef";
    document.write(str1+str2+"='#REPLY'>go to bottom</a>");
  </script>
(Writing "href" in one string makes php transform the address)
But when reloading the page with the reload button, the get arguments are added once again behind the address of the link. The link still works, but the page is reloaded again !

It should, or am I wrong?

the ?-part is of the page-part of it, and the # is for the section.

Doesn't ? go BEFORE the # in HTTP-specs? Can someone verify that, since I 'forgot' the RFC-nr ;-)

Since PHP is inserting it between, I'm quite sure it should go before, otherwise the person who wrote it wouldn't have taken the trouble to do so :)

Does your browser have problems with that?

Apache/1.3.14 Server at www.webcour.swisszone.ch Port 80

Works correctly (that "#bottom" is left alone) since oktober 2000 (version 1.17 of ext/standard/url_scanner_ex.re)
That means it worked since 4.0.4 exactly. (I only tested 4.0.7, so I'm not 100% certain)

And I was correct that # came _after_ the ?, so there's no bug (anymore).

Sorry, I put protection 777, but that was too much. Now it should work :

http://webcour.swisszone.ch/a/essais/session.php?f=1

You are right that there is no bug so far as concerns the position of "#bottom". I tried with Explorer 4.5: link no 1, 2 and 4 are OK, but still the page is reloaded. With Netscape 4.6 the first link does not work. Maybe it also depends on the reload preferences of the navigator. So all this is rather tricky, isn't it ?
But what about the following suggestion: php could refrain from inserting the session_id if the link contains only an anchor (like: href="#bottom"), because this means that the page is not to be reload.

"php could refrain from inserting the session_id if the link contains only an anchor (like: href="#bottom"), because this means that the page is not to be reload."

But that's exactly what it does (as of 4.0.4, according to CVS, tested that it works right with 4.0.4pl1)! Therefore, there is no bug in PHP>=404, see the html-source! (there was a bug, however, in PHP<=403

And PHP has nothing to do with how browsers handle things...

Thank you very much ! I'm sorry to have bothered you with my problem. I was sure I was working with php 4.0.4, but it actually was 4.0.3 and of course it didn't work properly.
