public Cookie(java.lang.String name,
java.lang.String value)
The name must conform to RFC 2109.
The name of a cookie cannot be changed once the cookie has been created.
The value can be anything the server chooses to send. Its value is probably of interest only to the server.
The cookie's value can be changed after creation with the setValue(String) method.
The version can be changed with the setVersion(int) method.
name - the name of the cookie.value - the value of the cookie.java.lang.IllegalArgumentException - if the cookie name is null or empty or contains any illegal characters (e.g.
a comma, space, or semicolon) or matches a token reserved for use by the cookie protocol.setValue(String),
setVersion(int)public void setComment(java.lang.String purpose)
purpose - a String specifying the comment to display to the user.getComment()public java.lang.String getComment()
null if the cookie has no comment.null if unspecified.setComment(String)public void setDomain(java.lang.String domain)
The form of the domain name is specified by RFC 2109. StandardCookieProcessor domain name begins with a dot
(.foo.com) and means that the cookie is visible to servers in a specified Domain Name System (DNS) zone
(e.g. www.foo.com, but not a.b.foo.com). By default, cookies are only returned to the server that
sent them.
domain - the domain name within which this cookie is visible; form is according to RFC 2109.getDomain()public java.lang.String getDomain()
Domain names are formatted according to RFC 2109.
setDomain(String)public void setMaxAge(int expiry)
StandardCookieProcessor positive value indicates that the cookie will expire after that many seconds have passed. Note that the value is the maximum age when the cookie will expire, not the cookie's current age.
StandardCookieProcessor negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. StandardCookieProcessor zero value causes the cookie to be deleted.
expiry - an integer specifying the maximum age of the cookie in seconds; if negative, means the cookie
is not stored; if zero, deletes the cookie.getMaxAge()public int getMaxAge()
By default, -1 is returned, which indicates that the cookie will persist until browser shutdown.
setMaxAge(int)public void setPath(java.lang.String path)
The cookie is visible to all the pages in the directory you specify, and all the pages in that directory's subdirectories.
Consult RFC 2109 (available on the Internet) for more information on setting path names for cookies.
path - a String specifying a path.getPath()public java.lang.String getPath()
setPath(String)public void setSecure(boolean flag)
The default value is false.
flag - if true, sends the cookie from the browser to the server only when using a secure
protocol; if false, sent on any protocol.getSecure()public boolean getSecure()
true if the browser is sending cookies only over a secure protocol, or false if the
browser can send cookies using any protocol.true if the browser uses a secure protocol, false otherwise.setSecure(boolean)public java.lang.String getName()
public void setValue(java.lang.String newValue)
If you use a binary value, you may want to use BASE64 encoding.
With Version 0 cookies, values should not contain white space, brackets, parentheses, equals signs, commas, double quotes, slashes, question marks, at signs, colons, and semicolons. Empty values may not behave the same way on all browsers.
newValue - the new value of the cookie.getValue()public java.lang.String getValue()
setValue(String)public int getVersion()
setVersion(int)public void setVersion(int v)
Version 0 complies with the original Netscape cookie specification. Version 1 complies with RFC 2109.
Since RFC 2109 is still somewhat new, consider version 1 as experimental; do not use it yet on production sites.
v - 0 if the cookie should comply with the original Netscape specification; 1 if the cookie should
comply with RFC 2109.getVersion()public java.lang.Object clone()
clone in class java.lang.Objectpublic void setHttpOnly(boolean isHttpOnly)
If isHttpOnly is set to true, this cookie is marked as HttpOnly, by adding the HttpOnly attribute to it.
HttpOnly cookies are not supposed to be exposed to client-side scripting code, and may therefore help mitigate certain kinds of cross-site scripting attacks.
isHttpOnly - true if this cookie is to be marked as HttpOnly, false otherwise.public boolean isHttpOnly()
