Query on Multiple http requests on single client - webdis connection

[srimithravemula]

Hi Nicolasff,

Have a query as following -
I was trying a small test case on sending multiple http requests on same client connection to webdis. I see response in any order for the provided requests. Sample example -
for key k1 -> value v1, key k2 -> value v2
if i query like GET/k1 and GET/k2 on same client connection to webdis, i can get response v1 and response v2 or reverse order(as response v2 first and response v1).
Problem i am facing is there is no way to map between request and response in this case.
Is there any option that webdis provides to map between request and response(like example - any http header i can add to store the request?)
Or is it not expected to send multiple http requests on same connection without waiting for response?
Can you please let me know.

Thanks.

Hi @srimithravemula, sorry for the late reply.
There are a couple of things that you could try, those are just what comes to mind now.

One would be to write a Lua script that returns both the key and the value when given a key, so that if you call the script with k1 it return [k1, v1] – v1 being the value under k1.

Another approach would be to request each one with a different (custom) Content-Type, if you can handle such replies. This feature is documented here. So you could query /GET/k1?type=k1 immediately followed by /GET/k2?type=k2. The response with Content-Type: k1 is for the first request. This is not ideal, but as a workaround I think it could help.

I hadn't considered this use case, but I agree that it's an issue. I can't really make changes to webdis at this time, so I'll see if some past contributor could look into it.
