Hello everyone,

My Apache has just got three strange requests from three different
addresses:

Might this perhaps be an attack for a known bug of some HTTP server?
Should I maybe even worry about this? (I am running Apache 1.3.12).

By the way, I performed the same request locally and got a 404 error
instead of the 400s reported in the log.

TIA, Lars
