Hello, I am currently developing a module to help libraries rewrite links to external databases, such as ProQuest and LexisNexis, routing those links through an EZProxy <http://en.wikipedia.org/wiki/EZproxy> or other proxy referral server. For example, consider a resource located at: http://www.books24x7.com/marc.asp?bookid=30164 If accessed from an on-campus IP address, the resource will be available to the student. However, if off-campus, the student would either have to use VPN to route all their internet traffic through a university IP address or use an proxy referral server, such as EZProxy. EZProxy is easier, so from the library home page, the link is rewritten to something such as: http://ezproxy.example-library.edu/login?url=http://www.books24x7.com/marc.a... This way, the student is presented with a login screen for authentication and then directed to the resource. An easy module to make... or so I thought. Given the custom_url_rewrite_outbound() function, this kind of stuff should be easy to do in Drupal, but it is not. The url() function in common.inc returns the $path variable without any attempts to call custom_url_rewrite_outbout(). All would be well, if line 1408 of common.inc added the same functionality to external links in the url() function as it does for internal links. It just needs 3 lines: if (function_exists('custom_url_rewrite_outbound')) { // Modules may alter outbound links by reference. custom_url_rewrite_outbound($path, $options, $original_path); } Other than applying a patch, does anyone know another way around this issue? I am not talking about Apache mod_rewrite or anything similar, Clean URLs, or the Path module and URL aliases. I am looking for a way to rewrite external URLs in anchor tags (links) without creating a wrapper function for url() or l()... or using JavaScript or AJAX. Thanks! MT
