  1. Do not subscribe to the submit service load balancer (SSLB). Your web server should still subscribe to the WSLB.
  2. I added a few fields to submit, which include a flag supplied by you (not the website visitor) in the submission to the submit service. This includes the wstechnology and the wsuser fields, which are the technology used on your webserver and your ry username.
  3. Do not use port 8080 for submission to the SSLB. That hardwires to the TA version of the submit service, and will not distribute to the subscribed submit service endpoints.

I do apologize for the confusion. I have not graded any submissions yet, so please correct your image and send it back in for pass off.

As always, holler with questions.]]> Lab 3 Details 2007-10-09T23:21:26Z 2007-10-09T23:20:20Z tag:classes.eclab.byu.edu,2007:/462//4.315 2007-10-09T23:20:20Z

In the meantime, you will not automatically be included in the load balancer rotation, as I'm having difficulty restarting Pound when I want to.

Welcome!

This class is the one place in the curriculum that you'll learn how to build applications that don't live on a single computer--applications like those that make the Web such a fun place.

I'd say "sit back and relax" but that wouldn't be truthful. Rather "sit up straight and get ready for a fast ride."

The links on the right hand side of this page will take you to the important information about the class. Here's a few highlights:

  • Don't buy the textbook--wait for my discussion on the first day of class.
  • Be sure to read the FAQ
  • Remember the schedule is a suggestion at this point and will change.
  • You need to create a blog for the class

I'm sure I'll think of some others. Watch this space for further developments.
