I am running a xampp server on windows 7 64bit localhost.

I was trying to download a site running on my localhost, such as
<http://localhost/mysite> and kept getting the following error messages:

16:42:42 Warning:  Cache: damaged cache, trying to repair
16:42:42 Warning:  Cache: 0 bytes successfully recovered in 0 entries
16:42:42 Warning:  Cache: error trying to open the cache
16:42:45 Error:  "Connect Error" (-4) after 2 retries at link localhost/mysite
(from primary/primary)

Finally, I tried <http://127.0.0.1/mysite/> (i.e. I changed the localhost to
127.0.0.1) and this worked fine!

Here's hoping that this helps someone else in the future.
