Hi I have found many resources on mod-rewrite and Apache but I haven't been successful of making a working example.

The example below works for

✓ WORKS (internal redirect)

✓ WORKS (redirect)

✓ WORKS (internal redirect)

✓ WORKS (redirect)

✓ WORKS (redirect)

✓ WORKS (redirect)

✖ FAILS (redirect - SHOULD BE

✖ FAILS (redirect - SHOULD BE

    <IfModule mod_rewrite.c>
        RewriteEngine   On
        DirectorySlash  On

        # Force hostname without www REDIRECT
        RewriteCond     %{HTTP_HOST}            !^example\.com [NC]
        RewriteCond     %{HTTP_HOST}            !^$
        RewriteRule     ^(.*)$                  http://%1/$1 [R=301]

        # /xx/somepage.php -> /somepage.php?ln=xx INTERNAL REWRITE
        RewriteCond     %{REQUEST_URI}          ^/../.+ [NC]
        RewriteRule     ^(en|de)/(.*)           $2?ln=$1&%{QUERY_STRING} [L]

        # /en -> /en/ REDIRECT
        RewriteCond     %{REQUEST_URI}          ^/..$ [NC]
        RewriteRule     ^(.*)$                  $1/ [R=302,L]

        # /somepage.php -> /en/somepage.php REDIRECT
        RewriteCond     %{REQUEST_URI}          !^/../ [NC]
        RewriteCond     %{ENV:REDIRECT_STATUS}  !=200
        RewriteRule     ^(.*)$                  /en%{REQUEST_URI} [R=302,L]

        # /en/ -> /en/index.php INTERNAL REWRITE
        RewriteCond     %{REQUEST_URI}          !^/../.+ [NC]
        RewriteCond     %{ENV:REDIRECT_STATUS}  !=200
        RewriteRule     ^(.*)$                  /$1index.php [L]

★ NOTE 1: R=302 is for debugging. On server it's actually R=301.

★ NOTE 2: It's on Apache 2.2 so the %{ENV:REDIRECT_STATUS} !=200 bits are trying to emulate the [END] flag of the later Apache 3.2.9.


★ EDIT: Here is more of the .conf file

<Directory /var/www/vhosts/>
    Options +FollowSymLinks -Indexes
    AllowOverride           All

    AddDefaultCharset       utf-8

    ErrorDocument           400             /error.php
    ErrorDocument           401             /error.php
    ErrorDocument           402             /error.php
    ErrorDocument           500             /error.php

    [above code here]

Where's the redirect to error.php coming from, the application? I think we're missing a step in the redirect process for the failing requests, since Apache isn't configured to send requests to error.php at all. – Shane Madden Jul 3 '14 at 0:26
Hi. Just added the error.php bit. It's standard redirection to a pretty page, I think it has no effect on the problem. Thanks – Everydaypanos Jul 3 '14 at 0:32
Can you disable that part for troubleshooting this? It's hitting some kind of error response, which shouldn't be happening; would be good to see what. Also check the Apache error log for anything relevant? – Shane Madden Jul 3 '14 at 0:34
Can you clear the log and try the two URLs that do not work as expected then post the log snippet in the question? – Belmin Fernandez Jul 3 '14 at 1:03
@ShaneMadden If I remove all ErrorDocument bits it breaks completely and for it goes to – Everydaypanos Jul 3 '14 at 1:05

You do not have to specify RewriteCond if you could specify the match in RewriteRule. For example:

    # /xx/somepage.php -> /somepage.php?ln=xx INTERNAL REWRITE

    RewriteCond     %{REQUEST_URI}          ^/../.+ [NC]
    RewriteRule     ^(en|de)/(.*)           $2?ln=$1&%{QUERY_STRING} [L]

Should work with just:

    # /xx/somepage.php -> /somepage.php?ln=xx INTERNAL REWRITE
    RewriteRule     ^(en|de)/(.*)           $2?ln=$1&%{QUERY_STRING} [L]

Walking through both URLs that do not work:

  1. Matches rewrite with # /en -> /en/ REDIRECT comment and the URI becomes /de/
  2. Does not match any other rule. Did you expect it to match the last two rules? They won't because of %{ENV:REDIRECT_STATUS} != 200.

Does accessing directly have different results than the above URL?

  1. Matches rewrite with # /xx/somepage.php -> /somepage.php?ln=xx comment and URI becomes blahblah.php?ln=de&othergetvars
  2. Nothing else matches

Can you show us the directives that configure the virtual directories?

Hi. folders /en/ or /de/ or /xx/ do not actually exist. For example there is only one /page1.php file, only one /error.php file, only one /index.php file. 1. Explicit statements would defeat the purpose above. This rule needs to be general. 2. I think you are wrong here. It matches all cases other than /xx/[something]. By that point in the apache-algorith if a URI is not properly formatted as we want it /xx/... it could only be just a /xx/. So we show the index.php... 3. See initial statement. Directories are virtual. – Everydaypanos Jul 3 '14 at 0:52
... 4. The code's purpose is to just show the de error page. So I guess it would go like: INTERNAL REDIRECT from -> – Everydaypanos Jul 3 '14 at 0:52
Here is a spit from the rewrite.log (level 3 logging) link – Everydaypanos Jul 3 '14 at 0:59
Ah, I missed the negation. – Belmin Fernandez Jul 3 '14 at 1:04
:) regex devil! – Everydaypanos Jul 3 '14 at 1:13
