Server response retransmission due to duplicate client request (duplicate MID)

Hello,

I have a case when remote modem-connected client does not hear response to its latest request, so it retransmits the request, with the same MID.

I thought this is handled in coap-rs library server code, but it seems it's not.

What's the usual solution to this - when request with the same MID is received from the same endpoint?
Should my (user) code on server side just re-execute the request handler again producing new response, or should it cache previous response and just resend the response?

I need clarification on this.

Thanks.

I think the response can be cached if the request with the same MID. The cache method you can find a similar in the Block-Wise Transfers module
