I'm using mod_rewrite to rewrite URLs like this:
By doing this in .htaccess:
RewriteEngine On RewriteRule ^([\d,]+)/foo/$ /foo.php?id=$1 [L,QSA]
It works fine, except for when "1,2,3,4" turns into a string longer than 255 characters, Apache returns a "403 Forbidden".
There is no problem visiting
foo.php?id=1,2,3,4 directly, even with a very long id string, however this isn't an option for me.
Is there some Apache or other setting I should tweak?
UPDATE: I turned RewriteLog on with RewriteLogLevel 9. With a short id string, I get several lines in my log file. But when the id string is greater than 255 chars., nothing is logged (seems as though mod_rewrite isn't even executing?).
