Sets a response header with the given name and date-value. The date is specified in terms of milliseconds since the epoch. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

Specified by:

setDateHeader in interface ILcdResponse

Parameters:

aName - the name of the header to set

aValue - the assigned date value

addDateHeader

public void addDateHeader(java.lang.String aName,

setIntHeader

public void setIntHeader(java.lang.String aName,
                         int aValue)

Sets a response header with the given name and integer value. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

Parameters:

aName - the name of the header to set
