Losing Session Data when switching http to https

Hi all, discovered an interesting Php feature observed when using custom session handlers ( - The one Ying from ZippyDesign wrote, but modified to use Pgsql.) I am using Php 4.0.2 ( and 4.0.3p1 ) with apache 1.3.14 on Redhat 7.0 ( with its openssl 0.9.5a bundle) A page of the sort <? include("session_handler.php"); session_start; $x = "test" session_register("x"); header(" Location : https://" . $HTTP_HOST . "/otherpage.php"); ?> produces the result $x = "" ( as opposed to "test" ) when the value of x is echoed in "otherpage.php" This seems only to happen when Php is compiled as DSO....( well actually I mean that I did not observe this with Php 4.0.2 compiled as a module into apache 1.3.12 on Redhat 6.2 with openssl 0.9.6 - a few differences in versions there....sorry ...) Changing the https -> http in to redirected URL "fixes" the problem - so does : <? include("session_handler.php"); session_start; $x = "test" session_register("x"); print("<meta http-equiv=\"refresh\" content=\"1;url= https://" . $HTTP_HOST . "/otherpage.php\""); ?> Looks like the header call is discarding any previous headers set up. I am not sure if this reproduces with the default "files" session handler ( will try it out )...
