Comment 1 for bug 890118

This applies to any request header (x-auth-token, etc) -- a space in the field-name will cause the header to be unrecognised.

 From http://tools.ietf.org/html/rfc2616:

       message-header = field-name ":" [ field-value ]

and
      field-name = token

and
       token = 1*<any CHAR except CTLs or separators>

Hence, the header field name should not have any spaces in it.

This should be closed as invalid of won't fix.
