Well the network is probably fast between you and your test server. And
if you try to view the files with the browser, it transparently
decompresses them for you, so you never really notice.

Also in another application , I have checked the entries that you have
specified for the compression on tomcat are already there. However, cudn't
see much difference in terms of performance.

Thanks & Regards,

Well, if memory serves right, websphere can do it in version 5 and up,
but i guess they call it http compression. You need to look in the
configuration or help section. It's also possible, but more difficult to
do it with a servlet filter.

My net surfing is not working today.
I did manage to view the main page but cudn't see the related links.

I understood what gzip does.However, I couldn't understand as to how can I
implement it in my application. I use IBM websphere server.  I don't know if
I need to get some tool etc.
For ex: we need to download winzip or similiar utility to zip the files.

What do we actualy do to implement such a thing.
Would you please explain the steps which we need to perform to enable gzip.

Thanks & Regards,
Meenakshi

Thank you for your reply.
I use websphere server. Do you have any idea what needs to be done in that?

Depens on which servlet container you're using. If it's tomcat, look in
server.xml, on a <Connector .. > you can add the following properties;

compression="on"
compressionMinSize="2048"
noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml"

Hi, 

You may like to refer to the book "Core Servlets and Java Server Pages" by Marty Hall. (www.coreservlets.com)
An online version is avalable at http://pdf.coreservlets.com/CSAJSP-Chapter4.pdf section 4.4.

Is it some tool that needs to be downloaded from some where.
