It is stated in RFC 7233 that "Servers are free to ignore Range, many implementations will simply respond with the entire selected representation in a 200 (OK) response." However, both the server and the client are Adobe-owned in this case, so Adobe has the right to not accept the full (200) response. The Adobe Updater client does not seem to support non-range responses (such as the 200 OK) and assumes that it will receive a range response ( 206 Partial Content) from the server, as the Adobe Updater servers support it. For this reason, the client must also handle a non-range response for a range request. This is in accordance with RFC, as the range requests can be requested by clients, but not all servers are required to support this. The WSA then sends a 200 OK message to the Adobe Updater client.This occurs so that the WSA can perform optimal Anti-Malware scanning. By default, the WSA converts this range request into a normal HTTP request and fetches all of the data (instead of specific bytes of data) from the Adobe Updater server.The range request is an HTTP request that includes headers such as Accept-Ranges: xxx and Range: xxx, which indicates that the request is for specific bytes of data only. The Adobe Updater is used in order to attempt a range request download from an Akamai-hosted URL.A packet capture that is taken on the WSA reveals this:
