The line:

$siteinfo[1] =~ /^[^.]+/(\w+\.\w+)$/ or ...

[download]

in Ovid's example has me confused. The extra slash (/) in the middle is throwing me off. At first glance, it looks like he meant to use the s/// operator. At second glance, it becomes apparent that it's meant as a directory separator (to exclude things like "../../". However, doesn't placing a '/' in a regexp delimited by '/' characters require an escape character (\)?

(I must be getting a mild case of LTS)

    Yes, you need to escape the / (with a \) or change the regex delimiter.

    Would be interested to see if the panel thought there's mileage in suggesting that it's unlikely that the user should want to open *any* type of file - and hence we could either assume an extension (and add it on explicitly before passing the filename to the ope() ?) - or offer a list, which would map to extensions (not just add on the field value (which could be faked to blank or a pipe)) Also - could the script not be forceably chrooted ?
