Hello,
I've just pushed a relatively minor change to the WAI spec to Github, which ties off the last hole in the specification I'm aware of. One annoyance in creating streaming responses is the issue of flushing. By using Builders, it's more difficult to make a truly streaming, realtime app, as the server will wait until a buffer is filled before sending any data to the client. This is actually a very easy problem to solve. blaze-builder provides a value called `flush` that forces the buffer to be sent, even if it's not full.
This sounds good. I updated all necessary libraries and tried to compile wai-app-file-cgi. I got the following error. ---- Couldn't match expected type `Flush Builder' with actual type `Builder' Expected type: Source IO (Flush Builder) Actual type: Source IO Builder In the third argument of `ResponseSource', namely `src' In the second argument of `($)', namely `(ResponseSource st hdr' src)' ---- I don't understand how to fix. Are there any example implementations for proxy? --Kazu
