ESI Reading and Reference Material

• Read chapter 2 of Aparna Yeddula's Master Project for a brief introduction on ESI specification.
• http://developer.akamai.com/esi_resources.html contains a set of ESI resources including the specification and ETS (ESI Test Server) servers.

Steps for installation and running ESI Test Server (ETS)

• Create esi directory under your public_html/cs526 directory.
• Go to the http://developer.akamai.com/esi_resources.html web site and download the Linux Version of the ETS server. The Linux Version downloaded file is 'ETS_1.1Beta1_Linux.tar.gz'
• Extract the installation files use
  'tar xzvf ETS_1.1Beta1_Linux.tar.gz' in your esi directory.
• Use the following when install and configure your ETS. Type "./install" to run the installation script.
  • Install ETS on in your /users/server/students/<login>/public_html/esi/ETS/ directory
  • choose the port 8<last3dgits of your SS#> to run your ETS server.
  • set cs.uccs.edu to be your original server, port 80.
  • turn on ESI Debugging
  • Congigure GEO settings? n
  • a to accept the host's settings.
  • n to add a Original Host?
  • i to install ETS
  • y to start the ETS server
  • Confirm to start the ETS if you are ready to run it.
• In the $ESI/conf/httpd.conf you will find it load the esi module.
  • LoadModule esi_module libexec/mod_esi.so
• Run the ETS on your designated machine similar to the homework#2.
• The $ESI/bin contains the apachectl script. You can use it to start, stop, restart the ETS.
  e.g., "apachectl start" to start the ETS server.
• To use the ETC server, you need to set the browser to use the ETS server.
  Select Tools | intenet options
  Select Connections tab and LAN Settings
  Check "Use a proxy server ..." option. Enter "sanluis.uccs.edu" in Address field and "8<last3digits of your SS#>" in Port field.
  Click OK.

ESI Web pages

• I have created a web page for testing the esi tags at http://cs.uccs.edu/~cs526/esi/esipages/esichoose.html
  which referesh every 5 seconds using <meta http-equiv="Refresh" content="5; URL="esichoose.html">
• esichoose.html contains the esi:choose, esi:include, esi:when, esi:otherwise tags.
  It will display a different title if the request is from 128.198.172.158.
• You can change that to the IP adddress of your machine for testing this customization feature.
• esichoose.html reference the fragments of web pages at http://cs.uccs.edu/~cs526/esi/orgserver/
• pagechange.pl in ~cs526/esi/orgserver can be run to change the content of color.html and runningText.html

<esi:choose>
<esi:when test="$(REMOTE_ADDR) =='128.198.172.158'">
<esi:include src="http://cs.uccs.edu/~cs526/esi/orgserver/viptitle.html"/>
</esi:when>
<esi:otherwise>
<esi:include src="http://cs.uccs.edu/~cs526/esi/orgserver/titlepage.html"/>
</esi:otherwise>
</esi:choose>

<table>
<tr>
<esi:include src="http://cs.uccs.edu/~cs526/esi/orgserver/color.html" ttl="5s"/>
<esi:include src="http://cs.uccs.edu/~cs526/esi/orgserver/runningText.html" ttl="10s"/> </tr>
