It seems that you are using an egg from CHICKEN version 3, which is pretty old and not maintained anymore. The /eggref/3 part in the URL indicates that it is a CHICKEN 3 egg. The current major version is 4. You can get it from http://code.call-cc.org Check http://wiki.call-cc.org/eggref/4/http-client for the http-client for version 4 of CHICKEN. You can install it with: $ chicken-install http-client `chicken-install' is the egg management tool for version 4. If you have `chicken-setup', you have a CHICKEN version 3. I hope that helps.
