RT::Extension::CustomizeContentType) ); Set( %ContentTypes, ( 't' => 'text/x-perl-script', 'psgi' => 'text/x-perl-script', ) ); =head1 EXAMPLE CONFIGURATIONS =head2 Microsoft Office Older versions of IE often upload newer Microsoft Office documents with the generic C MIME type instead of something more appropriate. This causes RT to offer the file for download using the generic content type, which confuses users and doesn't launch Office for them. You can fix that by L and using the configuration below: Set(%ContentTypes, 'docm' => 'application/vnd.ms-word.document.macroEnabled.12', 'docx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'dotm' => 'application/vnd.ms-word.template.macroEnabled.12', 'dotx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.template', 'potm' => 'application/vnd.ms-powerpoint.template.macroEnabled.12', 'potx' => 'application/vnd.openxmlformats-officedocument.presentationml.template', 'ppam' => 'application/vnd.ms-powerpoint.addin.macroEnabled.12', 'ppsm' => 'application/vnd.ms-powerpoint.slideshow.macroEnabled.12', 'ppsx' => 'application/vnd.openxmlformats-officedocument.presentationml.slideshow', 'pptm' => 'application/vnd.ms-powerpoint.presentation.macroEnabled.12', 'pptx' => 'application/vnd.openxmlformats-officedocument.presentationml.presentation', 'xlam' => 'application/vnd.ms-excel.addin.macroEnabled.12', 'xlsb' => 'application/vnd.ms-excel.sheet.binary.macroEnabled.12', 'xlsm' => 'application/vnd.ms-excel.sheet.macroEnabled.12', 'xlsx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'xltm' => 'application/vnd.ms-excel.template.macroEnabled.12', 'xltx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.template', ); Config contributed by Nathan March. =head1 AUTHOR sunnavy, Thomas Sibley =head1 LICENSE AND COPYRIGHT Copyright 2012 Best Practical Solutions, LLC.
