I'm trying to develop an external method that must do the following: 1. check for the existance of a request.cookie 2. set a reply cookie 3. check for variables in the query string Optionally, I'd like to be able to "set" a variable in an external method that could later be tested in DHTML, though this isn't quite as important. However even the most simple external method is giving me an error, read-only buffer, class from line 266 of ExternalMethod.py Does anyone know what this error means?  Is it going to be possible to do items 1 through 3 above in an external method? What about item 4? (I could do REQUEST.set() perhaps) Maybe I'm not importing all the modules I need to.. Which modules do I need to get at REQUEST and REPLY?
