Subject: -cache_control will never work as described
Download (untitled) / with headers
text/plain 972b
Hi Andy, System Spec: This is perl, v5.8.1 built for i686-linux Linux login.info-miner.de 2.4.20-019stab031.3.777-smp #1 SMP Mon Sep 1 21:41:58 MSD 2003 i686 unknown I was again experimenting with CGI::WML. My problem: I want to cache the generated output on the mobile. Which does not yet happens in my application, on every prev/ the script will be invoked once again, doubling the amount of kB which need to be transfered, making the entire app quite expensive, For that purpose, I was trying to write out the Cache-control information in the way you decribed it. But that will never work, since the allowed header information is tested/filtered in CGI. And Cache-control does not belong to the allowed header information, so no output is generated in that header line :( Maybe I will find the time to invent a solution, but I am not sure. By the way I have solved my problem with wml_to_wmlc. I just write first into a buffer and compile than. Regards, Thomas

No that wasn't the reason, it was just a sloppy analysis :) Show quoted text

Cache-control didn't worked be cause rearrange was build for HTML ! See comment in CGI.pm. In the header routine of CGI::WML you have to use CGI's unescapeHTML as follows to fix this bug: foreach (@leftover) { next unless my($header,$value) = /([^\s=]+)=\"?([^\"]+)\"?/; $leftover{$header} = $self->SUPER::unescapeHTML($value); } Regards Thomas
