There are times where the express transfer is used and the destination server has redirect entries in .htaccess files from an incomplete transfer process. This leaves .htaccess files with:
RedirectMatch \.(dynamiccontent|pl|plx|perl|cgi|php|php4|php4|php6|php3|shtml)$ http://sever.something.com/cgi-sys/movingpage.cgi
Those entries will need to be removed.
The following is a one-liner type of script that will find all .htaccess files in /home and then comment out a line that begins with RedirectMatch and contains dynamiccontent. If the users are in multiple mount points or in another location then /home will need to be changed.
for x in `find /home -name .htaccess`; do sed -i 's;^RedirectMatch \\.(dynamiccontent;#RedirectMatch \\.(dynamiccontent;' $x; done
After this has completed for each mount point with users there shouldn't be any sites loading with movingpage.cgi.
