How to handle mod-rewrite with a custom url scheme?

So here's my problem : I'm trying to do a redirection on a webpage with the htaccess file. This redirection will be towards a custom URL (i.e not something ike "http://..." but something like "myurl://...).

For now, I'm trying this on a little local apache server, in which I have a index.html page, a "test" directory and in this directory a .htaccess file and a test.html file.

Here's what's inside the .htaccess file :

Options +FollowSymLinks
RewriteEngine   On
RewriteBase /
RewriteRule     ^(.*)$ myurl://test$1 [R=302]

I think the problem probably comes from here, as I'm totally new at this and this is the first time I try to write into a .htaccess file. So, if this is not the proper way to do this, what is the proper way to do this then ?

Thanks to anyone who can help

The issue is related to the RewriteRule itself that checks the url scheme. From the source code mod_rewrite.c it reads only a subset of schemes:

Protocols Recognized by Mod_Rewrite

• ajp:// - Apache JServ Protocol
• balancer:// - Apache Load Balancer
• fcgi://
• ftp:// - File Transfer Protocol
• gopher:// - Gopher (protocol)
• http:// - Hypertext Transfer Protocol
• https:// - Hypertext Transfer Protocol Secure
• ldap:// - Lightweight Directory Access Protocol
• mailto: - The mailto URI scheme
• news: - News Protocol
• nntp:// - Network News Transfer Protocol
• scgi://
• ws://
• wws://

Indeed you can use RedirectMatch that doesn't check the protocol as follows:

RedirectMatch /(.*) myurl://$1
