c# - How to make keep-alive header response? -


i try make simple web api application , post.when response request:

 {     "status": "ok",     "headers":     {         "date": "fri, 18 aug 2017 16:50:38 gmt",         "transfer-encoding": "chunked",         "connection": "close",         "content-type": "application/json; charset=utf-8",         "server": "kestrel"     },     "body": "....",     "code": 200,     "protocol": "http/1.1" }

but want make "connection": "keep-alive", not "connection": "close" changed config.

startup.cs:

 public void configure(iapplicationbuilder app,                        ihostingenvironment env,                        iloggerfactory loggerfactory) {     loggerfactory.addconsole(configuration.getsection("logging"));     loggerfactory.adddebug();     app.usemvc();     app.usesession();     app.run(async (context) =>     {         context.response.headers[headernames.connection] = "keep-alive";     });                     }

but, "connection": "close" response.

any idea how change "keep-alive" setting?

http/1.1 defines "close" connection option sender signal connection closed after completion of response. example, connection: close in either request or response header fields indicates connection should not considered `persistent' after current request/response complete.

if trying achieve persistent connection, may want websockets.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
