Any variables that are used in the methods of a servlet are independant
of each request. So I could declare a variable in my doPost routine and
assign the value of the login parameter to that variable. This variable
will not be seen by the other requests going into the servlet. The only
time the variables are seen by other parts of the servlet is when they
are declared as class level variables. These variables should be
declared to be things that every invocation of the methods needs to see.
For Example: In the servlet I have developed, I read in a configuration
file to provide information about my database. I store this information
in class variables so I only have to read it in once(in the init).
When a user connects, I get his login name and his password. I store
these in variable I declared in the doPost method. I then run my
validation routines against the login name.
