apache - How to redirect to lowercase when specific url contains at least one capital letter -

i need redirect possible combinations of lower/uppercase url lowercase, 1 specific url example-url.

sample:

/example-url => /example-url /example-url => /example-url /example-url => /example-url

rewriterule ^example-url(.*)$ /example-url$1 [nc,r=301,l] cause redirect loop...

thanks help!

you can use lookahead make sure @ least 1 uppercase letter there (?i) flag make ignore-case after lookahead:

rewriteengine on  rewriterule ^(?=[^a-z]*[a-z])(?i)example-url(/.*)?$ /example-url$1 [r=302,l]

(?=[^a-z]*[a-z]) positive lookahead ensure there @ least 1 uppercase letter.
(?i) making rest of pattern ignore case.

an alternative without lookahead:

rewritecond %{request_uri} [a-z] rewriterule ^example-url(/.*)?$ /example-url$1 [r=302,l,nc]
