Using Apache REDIRECT_STATUS to allow custom ErrorDocument

108 views Asked by Gene Vincent At 23 September 2022 at 10:37

I have an Apache config that uses legacy access rules and CGI error documents.

ErrorDocument 403 /perl/dispay.pl?page=error403

SetEnvIf User-Agent "SomeOldUserAgent" badUA
Deny from env=badUA

The blocking of the user agent works fine, but unfortunately the Deny rule also covers the generating of the error page.

I would like to exclude the error page from the blocking to provide a dynamic error message.

I have tried to allow by REDIRECT_STATUS, but this doesn't work.

SetEnvIf REDIRECT_STATUS 403 errorPage
Allow from env=errorPage

Any ideas ?
