.htaccess question

comptech520 · 11-19-2009, 09:11 AM

Hi, I'm going to be upgrading a website and was hoping to allow 1 IP address to view it during the upgrade process (mine), and any other IP except mine to redirect to another page.

How can I do that with .htaccess?

use a combination rewritecond and rewrite rule
see
http://www.webweaver.nu/html-tips/web-redirection.shtml
and
http://httpd.apache.org/docs/1.3/mod...ml#RewriteRule

With this code, what does "RewriteRule \.html$" from part of the last line do?

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REMOTE_HOST} !^123\.45\.67\.89
RewriteRule \.html$ /alternate_page.html [R=302,L]

Hi,

This is not going to work. The regex \.html$ means everthing that ends in .html, so in your case when other people visit a html page they will be redirected to alternate_page.html, that also ends in .html, so you'll have a loop. Besides that everyone can see other stuff like images, php files etc.
You should use something like that:

Code:

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REMOTE_HOST} !^123.45.67.89
RewriteCond %{REQUEST_URI} !^/alternate_page.html$
RewriteRule ^(.*) http://%{HTTP_HOST}/alternate_page.html [L]

Regards

When I use this code, the idea works, but upgrade.html still shows in the main page that only my IP address can see. Any ideas on that?

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REMOTE_HOST} !^23.27.254.134
RewriteCond %{REQUEST_URI} !^/upgrade.html$
RewriteRule ^(.*) http://%{HTTP_HOST}/upgrade.html [L]

Don't get it. Isn't upgrade.html the page you want your users to be redirected?

comptech520 · 11-20-2009, 05:38 AM

Yes is is. My site is in PHP the IP block works but when I view it I see the website plus the upgrade.html embeded either behind my site or showing as part of the site. How can I fix that?

bathory · 11-20-2009, 05:49 AM

Still don't get it.
upgrade.html is under the document root of your site, so it's normal to see it, if you request it.
If you don't want the page to be under your document root, you can redirect the users to a vhost, or something like that. In that case you don't the 2nd line and the last line should be:

Code:

RewriteRule ^(.*) http://vhost.domain.com/upgrade.html [L]

comptech520 · 11-20-2009, 06:06 AM

Sorry about that, I'm good for maiking myself unclear.

When my IP is the only one allowed to see the site, I'm seeing both the site and the upgrade page at the same time.

The Block WORKS for everyone else!

Please see the attached files

It looks like for me also is too difficult to understand

Anyway, are these screenshots from your browser?
I guess that the 1st image is the upgrade page shown twice plus the index in the back and the 2nd is your site new index page
Could be a browser cache or else I cannot understand how this can happen
Well, unless you have coded upgrade.html in such a way to show all this.
What happens if you visit directly upgrade.html?

comptech520 · 11-20-2009, 08:15 AM

Screen shots are from my browser, I use SnagIt.

If I go DIRECTLY to upgrade.html, it works perfect.

Please see atached txt file for upgrade.html, maybe something is wrong that I overlooked.

bathory · 11-20-2009, 08:30 AM

My fault. It's not the upgrade.html that you have to look, but the index page.
You should also try to visit the faulty page directly and see what you get

comptech520 · 11-20-2009, 08:32 AM

I didn't understand that, can you say that a little clearer with step by step instructions?

bathory · 11-20-2009, 08:54 AM

I think that maybe I can see what happens:
From the upgrade.html, I see that you're using external http requests for the images in your page, so you get redirected to upgrade html
Try adding as another RewriteCond (changing domain.com accordingly):

Code:

RewriteCond %{HTTP_HOST} !^www.domain.com$ [OR]
RewriteCond %{REMOTE_HOST} !^23.27.254.134
RewriteCond %{REQUEST_URI} !^/upgrade.html$
RewriteRule ^(.*) http://%{HTTP_HOST}/upgrade.html [L]

and see what happens

comptech520 · 11-20-2009, 08:58 AM

Still the same thing
