When the webserver is behind a reverse proxy, $ENV{REMOTE_ADDR} is not
the actual remote client's address but the reverse proxy's address. The
actual remote client's address is available from an environment
variable. The name of this variable depends on the proxy, e.g. pound
uses $ENV{HTTP_X_FORWARDED_FOR}.
As suggested by tyatsumi on the wiki, all access $ENV{REMOTE_ADDR} now
happens via a new function which allows users to override it in their
config file.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
Wiki-provided correction, courtesy Bayle Shanks. Apparently, the
previous regular expression in this function failed to match the
Comment form's HTML. This patch corrects that! The reCAPTCHA widget
is now properly displayed by both the Comment and Edit forms.
Thanks, Bayle. (http://bayleshanks.com)
($ReCaptchaTheme): New option.
($ReCaptchaTabIndex): New option.
(ReCaptchaGetQuestionHtml): New function. Permits site-specific
customization of module-emitted HTML and CSS.
(ReCaptchaGetQuestion): Rewritten so as to leverage the two new options and
one new function.
