GET /undefined

what does that mean?

[Spica]

I have never seen entries of this type in my logs, but I have about 20 of these today. Can someone tell me what that means?

"GET /undefined HTTP/1.1" "http://www.mysite.com/file.htm" 404 302

Thanks!

Spica,

It could mean any of several things.

First, check the page on your site that appears in the quoted string on the right side of the log entry. It is possible that this page contains a link to a page called "undefined", and that it is being clicked-on or called.

If that's not the case, then this is likely some troublemaker probing your 404 response or just poking around on your site. You can either ignore it, or block those accesses by IP address. How you do that depends on what server you're hosted on and how it is configured.

HTH,
Jim

It could also be a badly written spider trying to spider your site and messing up the link parsing, so trying to call an invalid page.

I know I've generated similar log entries on occasion ;)

Thank you for the answers. I won't worry about it too much for now unless such entries start showing up often.
