And for the sake of review, here's an alternative summary of the class:

• basic HTML was discussed at first
• we then created Unix accounts and reviewed Unix commands
• your first lab was an exercise in creating and distributing an archive
• you recall how permissions were important, and we used chmod for that
• we then discussed what a web server is and we installed Apache (from an archive)
• we reviewed Apache's folders as we set httpd.conf up before starting it
• we worked with crontab and set up an automated server restart routine
• in the process we set some environment variables: $EDITOR, $PATH
• and then we described the essence we needed to know about Perl
• using this language we described the set of conventions that comprise CGI
• a protected folder was set up so we can turn in our homework assignments
• we started writing our first CGI scripts and keeping state was an issue
• but the first thing we wanted to investigate was giving input to the script
• we found out that hidden fields could be used to keep state in a friendly environment
• we worked out a basic CGI processor
• we then investigated object-oriented perl and the CGI.pm module
• we came up with a template for developing web scripts
• we used it with CGI.pm and then we introduced PHP
• PHP had sessions so we decided we could keep state server side
• server-side state can be kept with CGI if we store it in a database
• we investigated mysql and we said DBI.pm is the way perl accesses it
• we discussed keeping state in general and in mysql using perl's DBI module
• we then worked out some problems and took the midterm
• after the midterm we installed Tomcat
• we wrote our first servlets (with and without sessions)
• we discussed JSP (java server pages)
• and then we discussed Javascript and DOM (the document object model)
• mysql access from PHP was also demonstrated and we built a shopping cart
• we then discussed possible projects: web chat, Javascript shopping cart
• the web chat uses HTTP in a certain way, which reminded us of the experiments in lab four

At the end we listed a bunch of questions of the kind you might see on the exam.

Also please review your homework assignments:

2	Basic client-side state with CGI.pm	One
3	PHP (sessions and hidden fields)	Two
4	Server-side state with MySQL and DBI.pm	One
5	Servlets	Two
6	Java Server Pages	Two
7	Javascript and DHTML	One

• objects and event handlers in Javascript
• basic template for the last homework assignment (lab for this week)
