[Privoxy-users] Prevent Privoxy from Filtering Localhost

[Vanderdenduur]

Thanks Fabian,

following your suggestions, I formatted that way and it seems to work well.

   { 
+redirect{s@^(https?://)?[^,%]+\b(angular|backbone|dojo|ember|ext.core|jquery.ui|jquery|modernizr.min|mootools-yui-compressed|prototype|scriptaculous|swfobject|underscore.min)\b[^/]*\.js[^,%]*@http://localhost/~Nathalie/CommonJS/$2.js@} 
}

   { -redirect }
