Performance tuning of forms deployed on web

Question

This is regarding forms deployed on the Web.
When a form is deployed on the web, every call form
results in downloading of the all the images required
for the toolbar. Analyzing the OAS log files shows that
more than 90% of the http requests from client to the
middle tier comprise of requests for these images.
Is there a workaround to ensure that these images can be
stored in a .jar file or a .zip file so that whenever
these are required, the .jar or the .zip file is
downloaded, thus resulting in significant reduction
of network traffic?
Also, is it possible to determine if the client machine is
using HTTP 1.0 or HTTP 1.1? Since HTTP 1.0 used by the client
results in the invocation of a new instance for every image
to be retrieved on the Server. Would there be any work arounds
for situations as these?
Also, are there any other measure to improve performance of applications on the web?
Thanx in advance.

We had the same problem when we deployed forms on web using jinitiator.when we look at the console window we observed that the images are loading again and again.we found the problem was with the image properties
(animation and frame properties), which you can set using Paint shop Pro or some other software. if the animation is set to repeat indefinetly, then the image will b downloaded indefinetly based on the time you set in the frame properties. we set the animation property to load only one time and that solved our problem. Hope this will help.
