From RFC-1738: hostname = [ domainlabel "." ] toplabel domainlabel = alphadigit \| alphadigit [ alphadigit \| "-" ] alphadigit toplabel = alpha \| alpha *[ alphadigit \| "-" ] alphadigit alphadigit = alpha \| digit However: py> urlparse('https://foo\\bar/baz') ParseResult(scheme='https', netloc='foo\\bar', path='/baz', params='', query='', fragment='') The hostname's BNF doesn't allow for a backslash ('\\') character, so I'd expect urlparse to raise a ValueError for this "URL".

From RFC-1738:

hostname       = *[ domainlabel "." ] toplabel
domainlabel    = alphadigit | alphadigit *[ alphadigit | "-" ] alphadigit
toplabel       = alpha | alpha *[ alphadigit | "-" ] alphadigit
alphadigit     = alpha | digit

However:

py> urlparse('https://foo\\bar/baz')
ParseResult(scheme='https', netloc='foo\\bar', path='/baz', params='', query='', fragment='')

The hostname's BNF doesn't allow for a backslash ('\\') character, so I'd expect urlparse to raise a ValueError for this "URL".
