[Seaside] requestContext and extra data in the output

My question is about extra data I am seeing when using the
requestContext to send back JSon data for a web service.
I am using Seaside 3.0 in Pharo 1.1
My renderContentOn:html method is:
renderContentOn: html
| resultDictionary |
self requestContext
respond: [:response |
resultDictionary := Dictionary new.
createError isNil
ifTrue: [resultDictionary at: #listName put: listName.
resultDictionary at: #listUUID put: todoList uuid asString]
ifFalse: [resultDictionary at: #error put: createError class asString.
resultDictionary at: #reason put: createError asString].
response contentType: 'application/json'.
response nextPutAll: resultDictionary asJson].
When I call the url for this web service, I get (here is the verbose
output from curl)
curl -v http://localhost:8081/createList
* About to connect() to localhost port 8081 (#0)
* Trying 127.0.0.1... connected

Long story short, How do I get rid of the <html header data that is in
the buffer before I get a hold of the response to put my JSon data in
the stream? Should I re-initialize the response with a fresh buffer?
Thanks in advance,
Brian
