I downloaded the sample Scheme code from the project page and it doesn't run. What's wrong?
If you downloaded it before Monday, Feb 18, download it again. There were some lingering ^Ms in the original posted Scheme version. They are all gone now.
How do I check if I'm having the ^M problem?
Try running your script from the command line. If the first error you get is about a file not found, you likely have the ^M problem.
I can't get the posted Scheme sample file to run
One student had luck sending origin to extract-first-binding as a string rather thana symbol (this may have to do with how you saved the cookie, so it might not work for everyone).
I seem to get the cookie value instead of the form value in the Scheme version
When you call extract-first-binding, try sending (reverse bindings) instead of bindings as the argument.
If you want to look at the contents of the bindings (extract-first-binding just takes first of that list), you can use extract-bindings (same args as extract-first-binding) to get the list of all bindings, then print that out on the next form for debugging.
Do I need 2135net or net for the require-library?
2135net supports cookies; net does not. To use 2135net, you need the collection-paths lines from the sample cookie example.
I'm getting "Internal server eror"
That means you have a bug. Try commenting out lines until you find the offending line. Also try balancing parens to make sure you have the right number in the right places.
