Servlet authentication question?

The web site encourages a computer owner for any username along with password which includes a simple HTML PAGE type.The HTML mode article the actual username as well as password to a servlet We have.The servlet verifies the actual username plus password simply by querying the data source where username plus the MD5 in the password match up.Whenever it returns a row, after that this servlet redirects a computer owner into a command mother board.In any other case, that servlet transmits this mistake on the login web site.

The control cell encompass different probable AJAX message or calls to servlets of which change elements in the MySQL database.

The Concern:
Possibly there is a way to retailer this username as well as password you might say wherever alternative servlets own this information and not say to them (post/get) in addition to verify the internet every time
