Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion'

Alright so I need some help with a mercurial rewrite:

# Taken from http://www.pmwiki.org/wiki/Cookbook/CleanUrls#samedir
# Used at http://ggap.sf.net/hg/
Options +ExecCGI
RewriteEngine On
#write base depending on where the base url lives
RewriteBase /hg
RewriteRule ^$ hgweb.cgi  [L]
# Send requests for files that exist to those files.
RewriteCond %{REQUEST_FILENAME} !-f
# Send requests for directories that exist to those directories.
RewriteCond %{REQUEST_FILENAME} !-d
# Send requests to hgweb.cgi, appending the rest of url.
RewriteRule (.*) hgweb.cgi/$1  [QSA,L]

Open in new window


This must be an infinite loop somehow, any ideas?

> RewriteRule (.*) hgweb.cgi/$1  [QSA,L]
I understand there is no another handler serving hgweb.cgi as a special handler - right? It's plain CGI?
If so, then hgweb.cgi/$1 does not exist as well as $1 - right? And therefore is processes to hgweb.cgi/hgweb.cgi/$1 and again and again.

You have to break it somewhere,
either You need to pass the extras as cgi variable (url is the variable passed hgweb.cgi)
RewriteRule (.*) hgweb.cgi?url=$1  [QSA,L]

or stopping at hgweb.cgi seen (if hgweb.cgi is a handler)
RewriteCond %{REQUEST_URI} !hgweb\.cgi
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) hgweb.cgi/$1  [QSA,L]

Still yields;

[Sun Nov 21 17:25:21 2010] [client 70.57.173.81] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' t$

# Taken from http://www.pmwiki.org/wiki/Cookbook/CleanUrls#samedir
# Used at http://ggap.sf.net/hg/
Options +ExecCGI
RewriteEngine On
#write base depending on where the base url lives
RewriteBase /hg
RewriteRule ^$ hgweb.cgi  [L]
# Send requests for files that exist to those files.
RewriteCond %{REQUEST_FILENAME} !-f
# Send requests for directories that exist to those directories.
RewriteCond %{REQUEST_FILENAME} !-d
# Send requests to hgweb.cgi, appending the rest of url.
RewriteRule (.*) hgweb.cgi?url=$1  [QSA,L]

Open in new window


Also this does not work at all:

RewriteCond %{REQUEST_URI} !hgweb\.cgi
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) hgweb.cgi/$1  [QSA,L]

Open in new window

Hmm, should not. Can You try enabling Rewrite logging/debugging
http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritelog
And then check the log for rewrite performed actions.

Also, the "RewriteRule ^$ hgweb.cgi  [L]" would be better handled with "DirectoryIndex hgweb.cgi"

From the log it looks like "url=$1" works as expected, it finally prints
1.2.3.4 - duke [date] [code.zbuffer.biz/sid#2de8c08][rid#2e63268/initial/redir#1] (1) [per-dir /home/zbuffer/public_html/code/hg/] pass through /home/zbuffer/public_html/code/hg/hgweb.cgi
which means rewrite has done with this.
But it looks like it throws "unauthorized"?

Apart from the above, it looks like Yours original  .htaccess should be fine if You have configured apache with ScriptAlias (or ScriptAliasMatch) in main httpd.conf(or include) - have You?

Yes it is properly configured, yet mercurial still does not work. It fails over to http mode which is VERY slow.

Can You get the rewrite log from original htaccess?
You positive that "ScriptAliasMatch        ^/hg(.*) ..." is in effect(like apache was restarted)

OK, the log shows no infinite loop nor the error You mentioned. I don't think I can help You with that. Sorry.
