Method Detail

readCookieValue

java.lang.String readCookieValue(java.lang.String name)

Returns the value of the first cookie whose name matches. Returns null if no such cookie exists. This method is only aware of cookies that are part of the incoming request; it does not know about additional cookies added since then (via writeCookieValue(String, String)).

writeCookieValue

void writeCookieValue(java.lang.String name,
                      java.lang.String value)

Creates or updates a cookie value. The value is stored using a max age (in seconds) defined by the symbol org.apache.tapestry.default-cookie-max-age. The factory default for this value is the equivalent of one week.

writeCookieValue

void writeCookieValue(java.lang.String name,
                      java.lang.String value,
                      int maxAge)

As with writeCookieValue(String, String) but an explicit maximum age may be set.

Parameters:

name - the name of the cookie

value - the value to be stored in the cookie

maxAge - the maximum age, in seconds, to store the cookie

removeCookieValue

void removeCookieValue(java.lang.String name)

Removes a previously written cookie, by writing a new cookie with a maxAge of 0.
