Thanks Ben, here are the answers :

in .htaccess

no change with or without

I'll have a look now

I'll try that. Is it possible to set it in .htacces or must I change global apache configuration (I only have access to my .htaccess in this hosting).

Thanks

Hello
I received some clues from this list members, thanks for that. But
unfortunately my problem is not solved.

It's not that I want others to focus on me, but I'm quite sure that
there is a real problem (if not why would it work perfectly on mod_php
?), I could not find any solution googling about it (even with the help
of the host technical team), and I would like a confirmation that 1)
it's not an error from my understanding, and 2) there is no workaround
for it.

I doubt it is a problem with the software. mod_rewrite has been put
through the paces over the years and I'd be shocked if a bug were
uncovered given your rule's relative simplicity.

Before digesting your post in its entirety, I have a couple of questions
first.

1.) Where have you defined the rewrite rule? In a .htaccess file?

2.) Have you defined a RewriteBase? If so, what is it?

3.) Have you reviewed Apache's access log at all?

4.) Have you increased RewriteLogLevel to, say, 4, to see exactly what
the mod_rewrite engine is doing?

So I'll be very pleased to here from some qualified developer before I
spend 2 days to modify and retest all my application.

Thanks in advance.

Sorry to insist but I'm really blocked and I really need help.
Here is a small summary for those who don't want to read all :

I want to make a rewrite from :

http://www.perspectives-musicales.org/en/all-albums
to
http://www.perspectives-musicales.org/index.php/en/all-albums

my rewrite rule is

RewriteRule ^en/(.*) ./index.php/en/$1

This works when apache is runnnig with mod_php, but not when running
mod_fcgid (php as cgi). In cgi mode I have a 404 error.

The Apache version is 2.2.23 and mod_fcgid is version 2.3.7 with
configuration flag cgi.fix_pathinfo=1

Thanks for your help.

Hello
I'm new to apache mailing list, sorry if I'm not 100% clear, and sorry
for this long description.

I have developped a website with php/mysql :
http://www.perspectives-musicales.org and placed it on a good hosting
service (web4all.fr).
To improve search engine rank I decided to set all urls to
/index.php/... and rewrite them to avoid having index.php in url (sort
of MVC technique combined with SEO...)

Example : the catalog is at url :
http://www.perspectives-musicales.org/en/all-albums
This should be transparantly mapped to
http://www.perspectives-musicales.org/index.php/en/all-albums thanks to
the rewrite rule :

RewriteRule ^en/(.*) ./index.php/en/$1

My application uses then $_SERVER["PATH_INFO"] (and not
$_SERVER["QUERY_STRING"]) to retreive url information. This worked
perfectly until last month, because web4all.fr changed the whole system
and separated apache from php, using fast cgi instead of mod_php.

The system is supposed to be more reliable and more efficient like this,
and apparently is. But the rewrite rule does not work anymore. So I
investigated and made some test :

I have a small test.php that displays the path_info and query_string.
You can presently test it here :

http://perspectives-musicales.org/test1/a/b/c
http://perspectives-musicales.org/test2/a/b/c
http://perspectives-musicales.org/test3/a/b/c
http://perspectives-musicales.org/test4/a/b/c

and I set the following rules :

RewriteRule ^test1/(.*) ./test.php/$1
RewriteRule ^test2/(.*) ./test.php?$1
RewriteRule ^test3/(.*) ./test.php?/$1
RewriteRule ^test4/(.*)
http://www.perspectives-musicales.org/test.php/$1

None of these 4 rewrite rules are convenient. Here is why :

- test1 : the system anwsers 404 "No input file specified". I think (not
sure) that Apache beleives that test.php is a folder, and cannot find it
so answers 404

- test2 : the rewrite rule works, but of course the url information is
no more in path_info, it is in query_string as shown in the page content

- test3 : same as test2

- test4 : almost good, I can have the url info in path_info, but apache
begins first with a 302 redirection and then changes the url to
http://www.perspectives-musicales.org/test.php/a/b/c, which looses all
search engine efficiency (and also eventual POST variables if any).

My host tried several searches on forums including this one, and could
not find any answer. It seems to be an apache bug, but not sure, I have
no bug number to give anyway. If it is a bug, it is demontrated by test1
I think.

So here is my question : Is there any way to make this rewrite rule work
in fastcgi mode, and what is the syntax for it, to keep info in
path_info without 302 redirection. The Apache version is 2.2.23  and
mod_fcgid is version 2.3.7 with configuration flag cgi.fix_pathinfo=1

If there is a way, thanks for your help I'd be glad to test it. If no
could you explain why and how to solve it. As workaround we used test4
syntax in the whole site, to make it work, but it is bad for search
engine, and creates problem in backoffice (because certain backoffice
functions use POST variables)

I know I can change my code to use query_string everywhere instead of
path_info, but if I can avoid changing and testing all my websites it
would be really great

Thanks a lot for your anwser.
