# Using mod_rewrite to fix a problem when percent symbols are in
# the subject line of the OWA email (the email subject is used
# in the web query - WTF?). The entire URI is passed to a small
# bash script I wrote that replaces all occurrences of the % symbol
# with the URI escape sequence (%25). That seems to make everything
# happy.
