You may incorporate this servlet into your portal where your users will be authorized. In order to prevent access to files from not authorized visitors you may use authorized parameter in your config file. Servlet assumes that your authorization procedure will put some object into session (as a flag for authorized users). And name for this object should be described for FileManager as a parameter authorized. Servlet checks session and if there is no such attribute than request will be forwarded or redirected to the page, described as a parameter login.

If login value starts with http than request will be redirected to that site. Otherwise servlet assumes a local resource and forwards request.


1. You can save such configuration file anywhere on your server. Just use the proper path for setting servlet's parameter. Short path (just name of the file) means that your configuration file is saved under the root (docBase) directory of your container.

2. Evaluation version adds an exta © information to the edited file and restricts size for the uploaded files.
