Hi

How do I increase the buffer size for messages sent from the client using SignalR?

Hi,

On the server-side, you need to set GlobalHost.Configuration.MaxIncomingWebSocketMessageSize to a greater value (the default is 65536 bytes). You can put it for example in the "Startup" method.

Tried that, doesn't work.

Using the SignalR example given in:
viewtopic.php?f=7&t=8121&p=9451&hilit=signalr#p9451
https://github.com/cshtml5/CSHTML5.Extensions.SignalR

Added to Startup.cs:

Code: Select all

// Made the buffer size five times larger
GlobalHost.Configuration.MaxIncomingWebSocketMessageSize = 327680;

Tried to send the Message using the demo messaging app.

Checked size of message using:
System.Text.ASCIIEncoding.Unicode(GetByteCount(string);

Maximum size is 2624

Anything above that and the Server will not receive any data.

How can I fix this?
