Header: Poco/Net/HTTPCookie.h
Description
This class represents a HTTP Cookie.
A cookie is a small amount of information sent by a Web server to a Web browser, saved by the browser, and later sent back to the server. A cookie's value can uniquely identify a client, so cookies are commonly used for session management.
A cookie has a name, a single value, and optional attributes such as a comment, path and domain qualifiers, a maximum age, and a version number.
This class supports both the Version 0 (by Netscape) and Version 1 (by RFC 2109) cookie specifications. By default, cookies are created using Version 0 to ensure the best interoperability.

Constructors
HTTPCookie
HTTPCookie();
Creates an empty HTTPCookie.
HTTPCookie
explicit HTTPCookie(
const std::string & name
);
Creates a cookie with the given name. The cookie never expires.
HTTPCookie
explicit HTTPCookie(
const NameValueCollection & nvc
);
Creates a cookie from the given NameValueCollection.
HTTPCookie
HTTPCookie(
const HTTPCookie & cookie
);
Creates the HTTPCookie by copying another one.
HTTPCookie
HTTPCookie(
const std::string & name,
const std::string & value
);
Creates a cookie with the given name and value. The cookie never expires.
Destructor
~HTTPCookie
~HTTPCookie();
Destroys the HTTPCookie.
Member Functions
getComment 
const std::string & getComment() const;
Returns the comment for the cookie.
getDomain
const std::string & getDomain() const;
Returns the domain for the cookie.
getHttpOnly
bool getHttpOnly() const;
Returns true iff the cookie's HttpOnly flag is set.
getMaxAge
int getMaxAge() const;
Returns the maximum age in seconds for the cookie.
getName
const std::string & getName() const;
Returns the name of the cookie.
getPath
const std::string & getPath() const;
Returns the path for the cookie.
getSecure
bool getSecure() const;
Returns the value of the secure flag for the cookie.
getValue
const std::string & getValue() const;
Returns the value of the cookie.
getVersion
int getVersion() const;
Returns the version of the cookie, which is either 0 or 1.
operator =
HTTPCookie & operator = (
const HTTPCookie & cookie
);
Assigns a cookie.
setComment
void setComment(
const std::string & comment
);
Sets the comment for the cookie.
Comments are only supported for version 1 cookies.
setDomain
void setDomain(
const std::string & domain
);
Sets the domain for the cookie.
setHttpOnly
void setHttpOnly(
bool flag = true
);
Sets the HttpOnly flag for the cookie.
setMaxAge
void setMaxAge(
int maxAge
);
Sets the maximum age in seconds for the cookie.
A value of -1 causes the cookie to never expire on the client.
A value of 0 deletes the cookie on the client.
setName
void setName(
const std::string & name
);
Sets the name of the cookie.
setPath
void setPath(
const std::string & path
);
Sets the path for the cookie.
setSecure
void setSecure(
bool secure
);
Sets the value of the secure flag for the cookie.
setValue
void setValue(
const std::string & value
);
Sets the value of the cookie.
According to the cookie specification, the size of the value should not exceed 4 Kbytes.
setVersion
void setVersion(
int version
);
Sets the version of the cookie.
Version must be either 0 (denoting a Netscape cookie) or 1 (denoting a RFC 2109 cookie).
toString
std::string toString() const;
Returns a string representation of the cookie, suitable for use in a Set-Cookie header.
