i am currently mirroring a website.
while the mirroring is in progress, several pages are generated with a .tmp
extension

I investigated that some of the urls mentioned in the .tmp files contain a
very strange 00 Hex character inserted in the (otherwise valid URL). This
causes the webserver to respond with an error when I try to paste the URL into
a browser. After removing the 00Hex character from the URL, the page is
properly delivered from the webserver.

Example: <http://www.test.com>
