Stream: FHIR at Scale (FAST): Exchange with/without intermediaries
Topic: Response re-writing of URLs and References
Cooper Thompson (May 14 2021 at 19:57):
I'm participating in the endpoint directory track, so I'm not sure I'll be in the active discussions on the intermediary track, but I heard on the recording there was a subgroup working on the re-writing issue? It seems like there are four different categories of URLs that would need to be re-written:
- Location headers (e.g. on create interaction responses)
- Bundle fullUrls (on search interaction responses)
- Reference data types (specifically, literal references if using app paths, but also relative if using query strings).
- Other non-reference Uri types (e.g. attachment.url).
#4 seems especially tricky, since the attachment.url may or may not be related to the FHIR server. I'm not really sure how an intermediary could know whether it should re-write that except by checking if a substring of teh URL matches the URL of the FHIR endpoint.
