protected void setGetMethod(java.lang.String path)

Si l'on appelle la méthode requestEnabled<\code> avec comme paramètre true<\code> alors on dait préciser le type de méthode que l'on veut effectuer. Ici, On veut effectuer un Get.

setPostMethod

protected void setPostMethod(java.lang.String path)

sendHttpHeaders

public void sendHttpHeaders()

Envoie l'entête d'une réponse HTTP ou d'une requêtte HTTP Choix en fonction de la methode requestEnabled() Par défaut c'est uen réponse conforme au protocol HTTP.

writeHttpHeaders

public java.lang.String writeHttpHeaders()

Idem que sendHttpHeaders() mais l'entête est écrit dans un StringBuffer Pour pouvoir tester ou débugger

Returns:

String l'entête http que l'on s'apprête à écrire dans le flux

addCookie

public void addCookie(javax.servlet.http.Cookie cookie)

Specified by:

addCookie in interface javax.servlet.http.HttpServletResponse

Parameters:

cookie - the Cookie to return to the client

containsHeader

public boolean containsHeader(java.lang.String name)

Checks whether the response message header has a field with the specified name.

Specified by:

containsHeader in interface javax.servlet.http.HttpServletResponse

Parameters:

name - the header field name

Returns:

encodeURL

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

PAS IMPLEMENTE, PAS IMPLEMENTE, PAS IMPLMENTE 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 should include the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.

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.

Specified by:

encodeURL in interface javax.servlet.http.HttpServletResponse

Parameters:

url - the url to be encoded.

Returns:

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

encodeRedirectURL

PAS IMPLEMENTE ,PAS IMPLEMENTE,PAS IMPLMENTE 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 should include the logic to determine whether the session ID needs to be encoded in the URL. Because the rules for making this determination differ from those used to decide whether to encode a normal link, this method is seperate from the encodeUrl method.

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

After this method is called, the response should be considered to be committed and should not be written to.

Specified by:

encodeRedirectURL in interface javax.servlet.http.HttpServletResponse

Parameters:

url - the url to be encoded.
