Rich, PCRE searches against BODY can be very expensive, particularly when you
do a .* expression, which will try to match very long strings.
You can give your CPU a break by changing .* to a judicious text size
restriction e.g. .{5,100}
body 0 PCRE (?i:^http\:\/\/.{5,100}\.(html|htm|php)$)

body 0 PCRE (?i:^http\:\/\/.*\.(html|htm|php)$)
