Strange logs

href link truncated in IIS log file

[eric saunder]

Hi all,

I've spent 5 hours reading billion posts but nothing concerns this subject - i hope this is the place.

The log file from my IIS 5 Server reveals repeated 404 errors as if the first character of every href link was truncated: a link to default_sp.htm is interpreted as efault_sp.htm.

All error lines are generated from the same IP address(81.65.76.219) whose user agent is Mozilla/4.0+compatible;+MSIE+5.5;+Windows+98;+Win+9x+4.90).

Of course i've checked my links and did not notice any error. Some of them contains javascript <a href="default_sp.htm" onMouseOver="self.status='Spanish version';return true;" onMouseOut="self.status='';return true;"><img src="spanish.gif"></a>

Any suggestion welcome...

Sounds like the work of a crawler with some bugs in its code. I'd ban the IP.

Are the "+"s in the UA or does your stats program insert those? If the former, ban the user agent as well.

I agree it's a buggy spider and almost certainly nothing to do with you. I don't see any pressing reason to ban it, though, unless it's causing problems.

thanks all for your answers.
