我在<host>/Symfony/中安装了Symfony2，但在.htaccess使用默认/var/www/Symfony/web/时，我去了：
<host>/Symfony/web/app.php/hello/James
我被重定向到：
<host>/hello/James
我想重定向到：
<host>/Symfony/hello/James
我认为这与.htaccess：
RewriteCond %{REQUEST_URI}::$1 ^(/.+)(.+)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteRule .? %{ENV:BASE}app.php [L]
我对mod_rewrite
修改
# Use the front controller as index file. It serves as fallback solution when
# every other rewrite/redirect fails (e.g. in an aliased environment without
# mod_rewrite). Additionally, this reduces the matching process for the
# startpage (path "/") because otherwise Apache will apply the rewritting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex app.php
<IfModule mod_rewrite.c>
RewriteEngine On
# Redirect to URI without front controller to prevent duplicate content
# (with and without `/app.php`). Only do this redirect on the initial
# rewrite by Apache and not on subsequent cycles. Otherwise we would get an
# endless redirect loop (request -> rewrite to front controller ->
# redirect -> request -> ...).
# So in case you get a "too many redirects" error or you always get redirected
# to the startpage because your Apache does not expose the REDIRECT_STATUS
# environment variable, you have 2 choices:
# - disable this feature by commenting the following 2 lines or
# - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
# following RewriteCond (best solution)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app\.php(/(.*)|$) %{CONTEXT_PREFIX}/$2 [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .? - [L]
# The following rewrites all other queries to the front controller. The
# condition ensures that if you are using Apache aliases to do mass virtual
# hosting, the base path will be prepended to allow proper resolution of the
# app.php file; it will work in non-aliased environments as well, providing
# a safe, one-size fits all solution.
RewriteCond %{REQUEST_URI}::$1 ^(/.+)(.+)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteRule .? %{ENV:BASE}app_dev.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
# When mod_rewrite is not available, we instruct a temporary redirect of
# the startpage to the front controller explicitly so that the website
# and the generated links can still be used.
RedirectMatch 302 ^/$ /app.php/
# RedirectTemp cannot be used instead
