Hi, The recently announced cool tutorial on using Zinc made me read the Zinc code in a bit more detail. I must admit, it makes for a nice read. In the process, I stumbled across: knownHTTPMethods ^ #( "Standard HTTP 1.1 Verbs" GET PUT POST DELETE HEAD TRACE OPTIONS CONNECT PATCH "WebDAV verbs" PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK) I would propose to model these as classes (inheriting from ZnRequestMethod). If we would have such a hierarchy, then the following code: ZnSingleThreadedServer>>handleRequest: request ... request method = #HEAD ifTrue: [ response clearEntity ]. Could become something like: ZnSingleThreadedServer>>handleRequest: request ... request method clearEntityForSingleThreadedServerResponse: response ZnRequestMethod>>clearEntityForSingleThreadedServer: aResponse "nothing" ZnHeadRequestMethod>>clearEntityForSingleThreadedServer: aResponse aResponse clearEntity What do you think?
