1. To implement HTTP compression / caching, install and configure Oracle iPlanet Web Server 7.0.x for the bi_serverN Managed Servers (refer to document http://docs.oracle.com/cd/E23943_01/web.1111/e16435/iplanet.htm)

2. On the Oracle iPlanet Web Server machine, open the file Administrator's Configuration (obj.conf) for editing. (Guidelines for modifying the obj.conf file is available at http://download.oracle.com/docs/cd/E19146-01/821-1827/821-1827.pdf)

3. Add the following lines in obj.conf file inside <Object name="default"> . </Object> and restart the Oracle iPlanet Web Server machine:

#HTTP Caching

<If $path =~ '^(.*)\.(jpg|jpeg|gif|png|css|js)$'>
ObjectType fn="set-variable" insert-srvhdrs="Expires:$(httpdate($time + 864000))"
</If>

<If $path =~ '^(.*)\.(jpg|jpeg|gif|png|css|js)$'>
PathCheck fn="set-cache-control" control="public,max-age=864000"
</If>

#HTTP Compression

Output fn="insert-filter" filter="http-compression" vary="false" compression-level="9" fragment_size="8096"
