Hi devs,
Please find attached a very minor patch for slightly improved
diagnostics in htp.
Since late February, I've seen 75 requests from 18 sites fail to
retrieve a date header:
--8<---------------cut here---------------start------------->8---
cat /var/log/htpdate.log | awk '/Could not get any Date header from/{print $8}'| sort | uniq -c | sort -rn

--8<---------------cut here---------------end--------------->8---
I'm afraid I don't have any numbers on how often date header fetches
From the above sites _succeed_ so maybe not so useful.

Subject: [PATCH] When date header cannot be fetched, print URL too.
For easier diagnostics of failing servers.
