工作学习 / IT技术讨论 / Applet and SSL problem?Hi Java experts,
I'm currently involved in improving the performance of an existed program. It's an internet application. Some applets, created using VJ, are for displaying data extracting from an oracle database. It works fine when browsers (both Netscape and IE) connect IIS using http. But the performance degrades dramatically for IE when using https.
Has anybody met a similar problem? Any hints are appreciated.

By definition, https protocol has a bigger overhead than http.

It takes about 20 second to display pictures
and table when using Netscape with https;
but 5 minutes when using IE. What causes so much difference? Dear Jabber, any idea?

How do your Applet communicate with DB? Are there any middleware between DB and Web Server?

Using dll to connect Oracle DBTheir applets don't communication with DB directly. The flow of exchanging data is briefly
as follows: Browsers connect to ASP hosted
at IIS, ASP uses DLL(created by VC++) to query data from Oracle DB, then put data as a string back to http, and finally applets parse
the string data and draw tables and figures on browsers. Applets don't utilize NET or JDBC packages. How do you think? Thank you, jabber.

Is your Applet necessary here?
