Subject: Re: store info on client side
flat file
Hi,
Actually, my requirement boils down
to writing some information in the form of a flat text file in the client
machine. Can someone tell me how to write into a file on the client machine
from a servlet ?
Thanks,
Mohan
Maintaining client persistence
between requests is (I think) a function
of the web server you are using. If you absolutely
must be able to
handle
clients who have their cookies turned off, I can think of a few
ways:
1) Have your servlet write out a
bunch of hidden form elements with the
values you need, then put handlers in the receiving pages
to read them.
2) Have your servlet encode
ALL href links with name/value pairs (ie:
<A
HREF='nextpage.html?pref=something&who=something+else'>
(make sure you escape special
characters like spaces)
3) Not really an entirely
different option, but use either of the first
two to store a unique key which you create for the client
when they log
in, and then
write info to this record in a database. This has the
advantage of being persistent as long as you
need it (you could put in a
time as well, and decide when they've timed out) but obviously, you
need
a db.
