Redirect all urls to my default page

redirect www.google.com to my web-page

[mprabhu]

hi,
i am building a web server-client system. my web-server also has an authentication system where the registered users use a login page to authenticate themseleves.once they do,the proxy.pac gives them the proxy.
right now i am looking at a scenario where an unauthenticated user tries to log onto say www.google.com or www.webmasterworld.com ...he should be redirected to a default login page(http://10.219.80.2/login.html-this is my websever url).
could somebody tell me how it can be done?
thanx
regards,
manjunath

This is the same question I have open. I can get everything from the one site, but I have fooled around with the mod rewrite for 2 days.

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com
RewriteRule ^(.*)$ [mydomain.com...] [R]

This is what I currently have in the .htaccess, but with it I can't open any pages.

mprabhu,

If you will describe your project in more detail, you may get some help. I read your description, but I can't really tell what you are trying to do -- what function resides on what server, and how it is implemented. As such, I can't tell if the solution will be inside Apache or require a custom-scripted solution, or a mixture of both. Perhaps you could invoke mod_proxy if the user is not authenticated, and "map" all external URLs to a single internal "Please log in" page.

wifi,

As written, your code will redirect "mydomain.com" to "mydomain.com" using an external redirect. This results in an "infinite loop", so a page is never served (check your server error log for the message "Redirection limit exceeded..."). If you will post your code and a more detailed description of your goal in your original thread, you will probably get better advice.
