Sometimes, not often, I see these lines in the error log:
[Sun Feb 20 11:53:38 2011] [error] [client 89.123.45.38]
mod_rewrite: maximum number of internal redirects reached.
Assuming configuration error. Use 'RewriteOptions MaxRedirects' to increase
the limit if neccessary.
[Sun Feb 20 11:53:38 2011] [error] [client 89.123.45.38]
Request exceeded the limit of 10 internal redirects due to probable
configuration error. Use 'LimitInternalRecursion' to increase the limit if
necessary. Use 'LogLevel debug' to get a backtrace.
MEANING?
First of all, what does it mean? Does it mean that some users will see a broken page just because the limit of x redirects per page visit has reached?
SOLUTION?
I have mod rewrite to set up various beautifications of otherwise ugly /page.php?ln=de that are now /de/page etc… within those pages something like 20 PHP-generated images are also rewritten to nicer image urls. Does this mean I have to set the limit higher than the 10 mentioned here? Is that 10 per second or 10 per visit or?
How can I change it in htaccess?
Any hint to this error is much appreciated.
That usually means you have an error in your rewrites causing an infinite loop. The limit catches it from becoming infinite as a rule.
When it says:
That means in one request it has been rewritten 10 times. That is a lot, and unless you have very complex rewrite rules going on, you most likely have a loop occurring.
