Interface HttpServletResponse Method


Package javax.servlet.http

The servlet container creates an HttpServletResponse object and passes it as an argument to the servlet's service methods.

addCookie


public void addCookie(Cookie cookie)

Adds the specified cookie to the response. This method can be called multiple times to set more than one cookie.

Parameters

cookie - the Cookie to return to the client





addDateHeader

public void addDateHeader(java.lang.String name,
long date)

Adds a response header with the given name and date-value. The date is specified in terms of milliseconds since the epoch.
This method allows response headers to have multiple values.

Parameters

name - the name of the header to set
date - the additional date value



addHeader

public void addHeader(java.lang.String name,
java.lang.String value)

Adds a response header with the given name and value. This method allows response headers to have multiple values.

Parameters

name - the name of the header
value - the additional header value If it contains octet string, it should be encoded according to RFC 2047.

addIntHeader

public void addIntHeader(java.lang.String name,
int value)

Adds a response header with the given name and integer value. This method allows response headers to have multiple values.

Parameters

name - the name of the header
value - the assigned integer value

containsHeader


public boolean containsHeader(java.lang.String name)

Returns a boolean indicating whether the named response header has already been set.

Parameters


Name - the header name

Returns

True if the named response header has already been set; false otherwise

encodeRedirectUrl


public java.lang.String encodeRedirectUrl(java.lang.String url)

Deprecated. As of version 2.1, use encodeRedirectURL(String url) instead

Parameters

url - the url to be encoded.

Returns

The encoded URL if encoding is needed; the unchanged URL otherwise.

encodeRedirectURL


public java.lang.String encodeRedirectURL(java.lang.String url)

Encodes the specified URL for use in the sendRedirect method or, if encoding is not needed, returns the URL unchanged.
The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL.
Because the rules for making this determination can differ from those used to decide whether to encode a normal link, this method is separated from the encodeURL method.

All URLs sent to the HttpServletResponse.sendRedirect method should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

Parameters


url - the url to be encoded.

Returns

The encoded URL if encoding is needed; the unchanged URL otherwise.

encodeUrl


public java.lang.String encodeUrl(java.lang.String url)

Deprecated. As of version 2.1, use encodeURL(String url) instead

Parameters


url - the url to be encoded.

Returns

The encoded URL if encoding is needed; the unchanged URL otherwise.

encodeURL


public java.lang.String encodeURL(java.lang.String url)

Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged.
The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL.

For robust session tracking, all URLs emitted by a servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

Parameters


url - the url to be encoded.

Returns

The encoded URL if encoding is needed; the unchanged URL otherwise.



sendError

public void sendError(int sc)
throws java.io.IOException

Sends an error response to the client using the specified status code and clearing the buffer.
If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

Parameters


sc - the error status code

Throws

java.io.IOException - If an input or output exception occurs
java.lang.IllegalStateException - If the response was committed before this method call
