Re: strange "Couldn't resolve host" error
Date: Mon, 6 Jan 2003 11:06:58 -0800 (PST)
I had been using (py)curl 7.9 because at the time I
got started there wasn't an rpm created for libcurl
7.10, but I'll give that a try now.
From what I've figured out so far, the problem only
occurs if I have 'pycurl.FOLLOWLOCATION' set. It
seems like perhaps the server is providing a Location
header to the server's hostname, a domain which for
some reason my local DNS server can't resolve. So
curl fetches the page I requested (by IP), and sees a
'Location' header and tries to redirect. It can't
resolve that host, so it throws the "Couldn't resolve
host" error. Does that seem like a reasonable
If so, assuming this is still the standard behavior
w/ 7.10, would there be a way to configure my curl
instance to just return the initial page (and not
raise an exception) if there was a problem fetching
the re-direct page?
