<BR/>This class is an implementation of a Browser-like history
|
||
|
|
stack suitable to use in any Helma application. The difference
|
||
|
|
to a Browser's history is that this implementation ignores
|
||
|
|
POST requests and checks if Urls in the stack are still valid to
|
||
|
|
prevent eg. redirections to a HopObject's url that has been deleted.
|
||
|
|
Plus it is capable to create new "intermediate" history-stacks
|
||
|
|
and this way maintain a "history of histories" which is needed for
|
||
|
|
eg. editing sessions in a popup window that should use their own
|
||
|
|
request history without interfering with the history of the
|
||
|
|
main window.
