18.104.22.168 Message Flow for Icon and Resource File Requests
The message flow between a client and a server for requests for icon and resource file URLs that were specified in the XML file containing the resource list is shown in the following diagram. Icon and resource file URLs are specified in the XML schema definitions for <Icon> elements (section 22.214.171.124.6) and the <ResourceFile> element (section 126.96.36.199.9).
Figure 6: Message flow between TSWPP client and TSWPP server on requests for icon and resource file URLs
In the preceding figure, the XML file containing the list of resources has already been downloaded. The client is downloading the resource files and icon files that are defined in the XML file.
If the server provided an authentication cookie, the client MUST set the .ASPXAUTH cookie and the client MUST request the resource and icon files by using the resources that were returned in the XML file.
If the requested resource or icon does not exist, the server MUST return an HTTP "404 Not Found" error code [RFC7230].
