Problem with RewriteCond order and %n in RewriteRule

Hi,

Using 2.2.2 (free), with an .htaccess like this:

Code: 
<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteBase /

    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} gallery\_remote2\.php
    RewriteCond %{REQUEST_FILENAME} !/main\.php$
    RewriteRule .   -   [L]

    RewriteCond %{THE_REQUEST} \ /d/([0-9]+)-([0-9]+)/([^\/\?]+)(\?.|\ .)
    RewriteCond %{REQUEST_FILENAME} !/main\.php$
    RewriteRule .   /main.php?g2_view=core.DownloadItem&g2_itemId=%1&g2_serialNumber=%2&g2_fileName=%3   [QSA,L]

    RewriteCond %{THE_REQUEST} \ /v/([^?]+)(\?.|\ .)
    RewriteCond %{REQUEST_FILENAME} !/main\.php$
    RewriteRule .   /main.php?g2_view=core.ShowItem&g2_path=%1   [QSA,L]

</IfModule>
If you go to a URL like http://gallery.domain.com:8088/d/5245-14/something.jpg
then the second rule gets trigerred, but the %1, %2 and %3 are empty in the RewriteRule.

Here's what the log shows:

Code: 
2006-10-01 15:03:42.660	INFO	[66.130.250.120:61102-0#gallery.domain.com] [REWRITE] Cond: Match 'GET /d/5245-14/something.jpg HTTP/1.1' with pattern '\ /d/([0-9]+)-([0-9]+)/([^\/\?]+)(\?.|\ .)', result: 5
2006-10-01 15:03:42.660	INFO	[66.130.250.120:61102-0#gallery.domain.com] [REWRITE] Cond: Match '/var/www/html/gallery2/d/5245-14/something.jpg' with pattern '/main\.php$', result: -1
2006-10-01 15:03:42.660	INFO	[66.130.250.120:61102-0#gallery.domain.com] [REWRITE] Source URI: 'd/5245-14/something.jpg' => Result URI: '/main.php?g2_view=core.DownloadItem&g2_itemId=&g2_serialNumber=&g2_fileName='
2006-10-01 15:03:42.660	INFO	[66.130.250.120:61102-0#gallery.domain.com] [REWRITE] append query string 'g2_view=core.DownloadItem&g2_itemId=&g2_serialNumber=&g2_fileName='
2006-10-01 15:03:42.660	INFO	[66.130.250.120:61102-0#gallery.domain.com] [REWRITE] Last Rule, stop!
If I simply invert both RewriteCond lines like this:
Code: 
    RewriteCond %{REQUEST_FILENAME} !/main\.php$
    RewriteCond %{THE_REQUEST} \ /d/([0-9]+)-([0-9]+)/([^\/\?]+)(\?.|\ .)
Then it works fine:
Code: 
2006-10-01 15:01:06.148	INFO	[66.130.250.120:61078-0#gallery.domain.com] [REWRITE] Cond: Match '/var/www/html/gallery2/d/5245-14/something.jpg' with pattern '/main\.php$', result: -1
2006-10-01 15:01:06.148	INFO	[66.130.250.120:61078-0#gallery.domain.com] [REWRITE] Cond: Match 'GET /d/5245-14/something.jpg HTTP/1.1' with pattern '\ /d/([0-9]+)-([0-9]+)/([^\/\?]+)(\?.|\ .)', result: 5
2006-10-01 15:01:06.148	INFO	[66.130.250.120:61078-0#gallery.domain.com] [REWRITE] Source URI: 'd/5245-14/something.jpg' => Result URI: '/main.php?g2_view=core.DownloadItem&g2_itemId=5245&g2_serialNumber=14&g2_fileName=something.jpg'
2006-10-01 15:01:06.149	INFO	[66.130.250.120:61078-0#gallery.domain.com] [REWRITE] append query string 'g2_view=core.DownloadItem&g2_itemId=5245&g2_serialNumber=14&g2_fileName=something.jpg'
2006-10-01 15:01:06.149	INFO	[66.130.250.120:61078-0#gallery.domain.com] [REWRITE] Last Rule, stop!
Any reason for such a behavior ?
Is RewriteRule only supposed to be able to use the %n from the previous line, and no other RewriteCond lines ?

PS This is from a working Gallery 2 installation. The same Rewrite rules work fine on Apache 2, with both RewriteCond lines inverted or not.

Thanks.

Yes, current rewrite engine implement is like that. We will change our implementation to improve the compatibility with Apache.

Thanks for the bug report and analysis.
