Method Detail

getSavedRequestIdentifier

public static String getSavedRequestIdentifier()

Returns:

the SAVED_REQUESTS_IDENTIFIER

getSavedRequestKey

public static String getSavedRequestKey()

Returns:

the SAVED_REQUESTS_KEY

saveRequest

public static String saveRequest(javax.servlet.http.HttpServletRequest request)

Saves the data from a request and stores it in the current session. This method is not thread safe, and does not guarantee that saved requests are not overwritten, but given that this should only happen sparingly, and that each client uses his own session to save this kind of information, this is not a real issue.

Parameters:

request - the request to save

Returns:

the identifier of the saved request

getOriginalUrl

public static String getOriginalUrl(javax.servlet.http.HttpServletRequest request)

Retrieves the original URL requested before a detour. This method returns something different from null only when there's a srid parameter in the current request, indicating that there was another request which data was saved, related to the current request.

Parameters:

request - the current request

Returns:

the original requested URL that triggered a detour, or null if there isn't any original request information
