Do I have a misunderstanding about bigpipe? about bigpipe

[JMPerez]

The base idea of Bigpipe is that the pagelets are injected asynchronously, so none of them block each other. Actually, the way JS scripts are included makes the browser request them asynchronously.

You can try adding a delay in the generation of one of the pagelets, and see that the server still returns (and the browser renders) the other one first.

Actually I have tried it before，I set the pagelet 1 return the result immediately,and set the pagelet2 with a long-time delay ，but browser was waitting for data until pagelet2 return the result

Like you mentioned fragment of javascript,I know BigPipe will send the data into browser with padding like "JSONP" method.I think that is what we need——“Chunked” and “Asynchronization”.

But,Javascript can only operate the data what has be sent (or flushed by server).I will test it more,I hope we can share more information,Let me thank you in advance.

As you can see,I set two pagelet with a different interval.And browser show the message like this below.

OK,After many searching,I found the point:gzip compression.

I turn off the gzip in web.config,now It's worked.

Anyway,thank you for your post again.
