Mod Rewrite 500服务器错误问题

Question

Overview

I'm trying to rewrite:

• http://www.foo.com/bar to the secure version https://www.foo.com/bar, then
• https://www.foo.com/bar to https://www.foo.com/index.php?location=bar

My index.php page simply outputs the $_GET variables.

Code

.htaccess:

RewriteEngine On
RewriteBase /
RewriteRule ^https://%{SERVER_NAME}%{REQUEST_URI} [L,QSA,R=permanent]
RewriteRule ^([^/]*)$ /?location=$1 [L]

index.php:

<?php print_r($_GET); exit; ?>

Issue

1. If I visit www.foo.com/bar, I see a 500 Server Error.
2. If I comment out the rule for handling the $_GET "location" variable and visit foo.com, it doesn't redirect to the secure version of the site.

Update

.htaccess:

RewriteEngine on

# if https is off (it is on)
#RewriteCond %{HTTPS} off
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

# If the request is not for a valid directory
RewriteCond %{REQUEST_FILENAME} !-d
# If the request is not for a valid file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/?$ ?location=$1 [L,QSA]

Visiting the following results in a redirect loop error:

• www.foo.com/bar
• www.foo.com/index.php?location=bar
• www.foo.com/?location=bar
• www.foo.com?location=bar

However, if I comment out this line:

RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

the page loads as expected:

Array ( [location] => bar )

This leads me to believe that the issue lies with the HTTPS redirect, how can I solve this?

Answer 1

This rule is the problem:

RewriteRule ^https://%{SERVER_NAME}%{REQUEST_URI} [L,QSA,R=permanent]

As syntax is

RewriteRule matching-pattern target [flags]

Also you need to RewriteCond in both rules to avoid rules looping.

You can fix it by replacing your code with:

DirectoryIndex index.php
RewriteEngine on

# if https is off
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [L,R=301]

# If the request is not for a valid directory
RewriteCond %{REQUEST_FILENAME} !-d
# If the request is not for a valid file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/?$ ?location=$1 [L,QSA]
