What's making these http requests give a 408 timeout?
My Apache server logs have been showing an increasing number of timeout responses all this month. I've had no luck catching them with rewrite rules, not even rewriting EVERY http request. No further request info can be obtained.
Here's a few sample log entries, all others are identical except for host and date fields:
The trailing "-" immediately after the domain name is always there, for these 408 response codes. Server load is light. It looks like probing with invalid http requests. Particularly because ip's are mostly different, assuming they are valid.
Is anybody else seeing this too? Thanks for any info.
