Odd URL problem

Hello all: I'm seeing an odd problem after I moved a large PHP application from one server to another. Part of the system sends an email to users, containing a clickable http:// link. The link includes a parameter called "goto", which bundles up a set of name-value pairs, which indicate the user's final destination. If the user isn't logged in yet, the application holds onto the goto parameter, and once the login is complete, forwards the user on to the specified location. When we send the url, it is encoded, and looks like this: http://foo.bar.org/goto.php?goto=area%3Dpersonnel%26sub%3Dpersonnel%26person nel%3D1002566%26option%3Dedit Once I moved the application, from a PowerMac G4 running LinuxPPC, Apache 1.3.20 and PHP 4.0.5, to a Dell PowerEdge running RedHat 7.3, Apache 1.3.26 and PHP 4.0.6, these URLs seem to not get translated any more. On our development server, Dell server running RedHat 7.1, Apache 1.3.23, PHP 4.1.1, they seem to work fine. When it works, I click an encoded link in my mailer, and my browser tries to access the URL with a correct, decoded query string. When it fails, I get a message from the browser (IE 5+ only for this app) that says "Attempt to access http://foo.bar.org/goto.php?goto=area%3Dpersonnel%26sub%3Dpersonnel%26person nel%3D1002566%26option%3Dedit failed". So it seems that the browser in the failing case is trying to deal with the URL in its encoded form. Anyone have any ideas about what I'm missing? -- Steve ======================================================= Steve Lane Vice President The Moyer Group 833 West Chicago Ave Suite 203 Voice: (312) 433-2421 Email: slane@moyergroup.com Fax: (312) 850-3930 Web: http://www.moyergroup.com =======================================================
