Re: Re: Re: Alternatives to PerlTransHandler?

I see, so it is per-user skinnable. Those links you gave use cookies. If that's acceptable, then I offer the following solution (only tried on Mozilla). It sets a cookie, then uses a Server-side includes to choose which skin to display. The sample CGI script uses CGI.pm. It's not the best solution I guess, but it's somewhat amusing at least. :)

ssi-cookie.html

<HTML>
<BODY>

<A HREF="/cgi-bin/skin-cookie.pl">Skin this</A><BR>

<!--#if expr="${HTTP_COOKIE} = /skin\=wacky/"-->
wacky
<!--#elif expr="${HTTP_COOKIE} = /skin\=goth/"-->
goth
<!--#else -->
minimal
<!--#endif -->

</BODY>
</HTML>
