SoupAuthupdate

gboolean
soup_auth_update (
  SoupAuth* auth,
  SoupMessage* msg,
  const char* auth_header
)

Updates auth with the information from msg and auth_header, possibly un-authenticating it.

As with soup_auth_new(), this is normally only used by SoupSession.

`msg`	`SoupMessage`
	The `SoupMessage` `auth` is being updated for.
	The data is owned by the caller of the function.
`auth_header`	`const char*`
	The WWW-Authenticate/Proxy-Authenticate header.
	The data is owned by the caller of the function.
	The string is a NUL terminated UTF-8 string.

Returns:	`gboolean`
	`TRUE` if `auth` is still a valid (but potentially unauthenticated) `SoupAuth`. `FALSE` if something about `auth_params` could not be parsed or incorporated into `auth` at all.
