One would expect that to be true. But when I do info = e.info(), info is
<httplib.HTTPMessage instance at 0x85bdd2c>.
When I print e.info(), I get the following:
Content-Type: text/html
Connection: close
WWW-Authenticate: Basic realm="xxxx"
Content-Length: xx
I can iterate through e.info() with a 'for' loop, but all I get as a
result is:
connection
content-type
www-authenticate
content-length
In other words, I get the headers but not the corresponding values.
The same also happens if I iterate through e.headers.

I checked out this site, but it didn't have any further information than
I had found on another site.
Any further suggestions?
