SAIF.Services.WCF.Host overview

SAIF.Services.WCF.Host is a shared infrastructure host that exposes six unrelated SOAP capabilities under one IIS application: raw file access, user/application preference storage, transient cross-application session handoff, imaging queue management, fax dispatch, and identity/authorization resolution. Callers reach each capability at its own route; there is no shared operation surface between the six.

Purpose

  • Provide file, preference, session-context, imaging, fax, and identity/authorization services to other SAIF applications over SOAP, backed by Oracle and SQL Server.

Business context

This host underpins several unrelated cross-cutting concerns for other SAIF applications: FileService and ImagingService support document handling workflows, PreferenceService and WebContextService support UI-adjacent session and preference persistence for calling applications, FaxService supports outbound fax delivery through the legacy fax gateway, and SecurityService is the provider side of the authorization calls other SAIF applications make against IsAuthorized/IsAuthorized2 and the various user-resolution operations.

Message format

Aspect Finding
Message encoding SOAP 1.1 over HTTP (basicHttpBinding, default unnamed binding)
Serializer Not observable — the contract assembly is external, so whether operations are attributed with DataContractSerializer or XmlSerializer semantics cannot be confirmed from this repository **
Message size limits maxBufferPoolSize="2147483647", maxReceivedMessageSize="2147483647", readerQuotas (maxDepth=32, maxStringContentLength=5242880, maxArrayLength=2147483647)
Metadata document ?wsdl published (<serviceMetadata httpGetEnabled="true"/>)

Non-documented artifacts

  • This host contains no .aspx, view, controller, or UI artifact of any kind; its entire surface is six ServiceRoute registrations over WCF service classes, and the AppType: web pipeline marker does not indicate a web UI.

Note: Statements marked with ** could not be confirmed; treat as unknown until verified.
