/*
|
||||
* The default number of simultaneous server connections is 4. Multiple connections can be triggered
|
||||
* by requests for embedded images, style sheets, icons, etc. and a TCP RESET is issued when no more
|
||||
* connections are available.
|
||||
* The Firefox default connections per server is 15. It can be reduced to 1 in about:config and generally
|
||||
* will improve throughput in the half-duplex 6LoWPAN link as embedded files will be requested sequentially.
|
||||
* Tictactoe is a good test for multiple connections; it can use as many as 9, but should also work when
|
||||
* Firefox network.http.max-connections-per-server is set to a lower number.
|
||||
* The RAM needed for each entry depends on script enabling and buffer sizes; see struct httpd_state below.
|
||||
* Typical range is 100 - 200 bytes per connection
