htaccess“如果文件存在”和“ mod_rewrite -f”不起作用

Question

I have some problems with a Cache Plugin for ProcessWire but maybe this is a more global question about apache .htaccess restrictions.

Example:

I call my page like this: http://example.com/foo The .htaccess should look up if there is a file DOCUMENT_ROOT/cache/foo/index.html If the file exists, then show the file, or - simplified for this example - just call a success page

Example File structure:

cache/foo/index.html (some dummy content)
bar (some dummy content)
file-found.php (the success page with some print_r($_SERVER) stuff)
.htaccess with this content:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{DOCUMENT_ROOT}/cache/$1/index.html -f
    RewriteRule ^(.*) file-found.php
</IfModule>

This works properly on my local machine ([SERVER_SOFTWARE] => Apache/2.4.18 (Unix)) But not with the hosting package where I want to use. ([SERVER_SOFTWARE] => Apache/2.2.31 (Unix)) The reaction of the server is just a 404: "The requested URL /foo was not found on this server."

Is it not working because of the version of apache or is it restricted by the hoster?

Btw. the ModRewrite basically works with this hosting. For example like this:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^(.*) file-found.php
</IfModule>

if i call http://example.com/bar , file-found.php is shown

Any ideas how to alternatively solve this "if file exists => then" rule in the htaccess?

Thanks for help!

EDIT: even more simplified:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{DOCUMENT_ROOT}/bar -f
  RewriteRule ^(.*) file-found.php
</IfModule>

works local, but not on hoster

Answer 1

I think that in RewriteCond the special characters should be escaped with \\ (if that whole phrase is not in double quotes)

in RewriteRule did you try to add flags, like [L] or etc..

Answer 2

Try this (you may need RewriteBase / ):

RewriteCond cache%{REQUEST_URI}/index.html -f
RewriteRule ^[^/]+(?:/[^/]+)*$ cache/$0/index.html [L]
RewriteCond cache%{REQUEST_URI}index.html -f
RewriteRule ^(?:[^/]+/)*$ cache/$0index.html [L]
