Default filter positions

EProtocolHandler The Protocol Handler :- At the base of the filter chain and nearest to the transport layer ECache Filters to handle caching behaviours. EStatusCodeHandler Filters to handle particular status codes. e.g.Redirection and authentication. EUAProf The UAProf filter. ECookies The cookie filter, and other filters that don't need to be concerned with resubmitting of transactions due to things like redirection. ETidyUp The validation filter and any other final tidy up or initial preprocessing of transactions EClientFilters Client filters that assume all standard behaviour is already there. EClient The client :- At the head of the filter chain : No position above this must be used.
