The following will:
1) define lc as a lower case function
2) check for desired URI and replace "$" with "/query string"
3) change first upper case letter to lower case (e.g. CamelCase to
camelCase)
Up to this point, the log file shows everything working as expected.
4) check for next camel case and change to lower case with preceding
underscore - (e.g. camelCase to camel_case )
This fails with log file output as shown in previous message.
RewriteMap lc int:tolower
RewriteCond %{REQUEST_URI} ^/cgi-sys/cgiwrap/guille/wiki.pl$ [NC]
RewriteRule .* /cgi-sys/cgiwrap/guille/wiki.pl/%{QUERY_STRING} [NS]
RewriteCond $1 ^/cgi-sys/cgiwrap/guille/wiki.pl/([A-Z])(.*)
RewriteRule ^(.*)$ ^/cgi-sys/cgiwrap/guille/wiki.pl/${lc:%1}%2 [NS]
RewriteCond $1 ^/cgi-sys/cgiwrap/guille/wiki.pl/(.*)([a-z])([A-Z])(.*)
RewriteRule ^(.*)$ ^/cgi-sys/cgiwrap/guille/wiki.pl/%1%2_${lc:%3}%4 [N,NS]
Can you verify if you get the same result if you put that regex on its own in a RewriteRule (rather than in a big chain)? There is some possibility that this is a PCRE issue (the regex engine used by apache) with greedy processing. (It may not be backtracking to match the third group after it already matches the first and second.) If so, you could probably work around it by using ...wiki.pl/([a-z]+)([A-Z])(.*) in your regex (and obviously changing your substitution variables to match). And as a bonus, that regex should be substantially faster since it doesn't require all the back-tracking to find a match.
