## Member Functions

### fromAuthInfo

void fromAuthInfo(
const std::string & authInfo
);

Creates an HTTPAuthenticationParams by parsing authentication information.

### fromRequest

void fromRequest(

void fromResponse(
const HTTPResponse & response,
const std::string & header = WWW_AUTHENTICATE

### getRealm

const std::string & getRealm() const;

Returns value of the "realm" parameter.

const HTTPAuthenticationParams & authParams
);

Assigns the content of another HTTPAuthenticationParams.

### setRealm
