Notice to IE and other, excluding Firefox

[huyhoa]

Hi!
I have a problem and wondering if some one could help me (especial richard ).
I have a forum at http://mysite.com/forum and all visit much visit it throught http://mysite.com (all non referrer or not mysite.com referrer will move to mysite.com then after click to link on mysite.com to go to mysite.com/forum)
I have this code to do it.

Code: Select all

Options +FollowSymLinks

RewriteEngine On

RewriteCond %{HTTP_REFERER} !^http://(.+\.)?mysite\.com(/.*)?$ [NC]
RewriteRule \.(txt|zip|pdf|exe|rar|pps|avi|wmv|mpg|html|php|asp|jsp|htm|gif|png|jpg)$ /index.php [NC,L]

So, now i want, when user use firefox, it work (i mean do it as it will be), but when user use other browser like IE, opera.... (all other) it will move to a notice site (like mysite.com/notsupport.php) then if use still want to use their browse, they can click to a link to go http://mysite.com/forum
If they direct access to mysite.com/forum then it will move to mysite.com/index.php but when go to index.php, it will check user browser then if firefox it display, if it's not firefox, it will move to mysite.com/notsupport.php then click to a link to go to mysite.com/forum, and so on
I'm sorry if my ideas is not clearly and my bad english.
Thank you so much for your help.

Why?

You can match the HTTP_USER_AGENT like the above matches against the HTTP_REFERER.

I dont know which one is right, firefox or mozilla

Neither do I. A search for "firefox user agent -switcher" found UserAgentString.com - List of Firefox User Agent Strings.

Thanks richardk. So, is this allright? i try but it's not work

Code: Select all

Options +FollowSymLinks

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} !^Mozilla$ [NC]
RewriteRule \.*$ /notsupport.php [NC,L]

Is there anything wrong here?
Can you please help me repair it?

Code: Select all

^Mozilla$

matches only "Mozilla" because it has ^ (the beginning) and $ (the end). You could want to remove the ^ and $ so it will match anything containing Mozilla.

!^Mozilla$

"Mozilla" won't work, look at, for example, Internet Explorer's user agent. Other browsers (some here) might have a user agent containing Firefox.

Code: Select all

RewriteRule \.*$ /notsupport.php [NC,L]

will also match the request to /notsupport.php and cause a loop. You need

Code: Select all

RewriteRule !^notsupport\.php$ /notsupport.php [L]

Well, thanks richardk.
I try this:

Code: Select all

RewriteCond %{HTTP_USER_AGENT} !Firefox [NC]
RewriteRule !^notsupport\.php$ /notsupport.php [L]

Then, it's work, but, have a problem.
Because it check user agent, so it cannot load images, css, .... when it display notsupport.php page, and when go to mysite.com/forum too.
I dont know how to fix it. Could you please take a moment to fix it for me?
Thank you so much!

Add exceptions, eg.

Code: Select all

RewriteCond %{REQUEST_URI} !^/path/to/style.css$

Thank for your reply.
But what's matter if i use many styles file and images too.
How do i add exception for all images file and style file?

[richardk]

Are they in a specific directory?
Do they have specific file extensions?
