Method for querying multiple access_token?
Web Programmer
There isn’t a way to request multiple character blobs, nor will there probably be in the future (the backend that the API talks to for character data also follows a request/response protocol and only supports one blob/request).
I’m not sure if our HTTP implementation supports pipelining, but pipelining the HTTP requests across a handful of persistent connections would be the fastest way to get the data out. Not sure if your HTTP library supports it, but I know cURL does, at least.
The main latency overhead from sending multiple requests is going to be the SSL handshake though, so even without pipelining re-using the connections is going to be a significant difference over using a connection/request.
