c# - RestSharp - Service Unavailable - Maximum number of active clients reached -

i'm using restsharp communication web service.

i use code

public static object gettagvalue(string url, string tagname, out string resp) {     object result = null;     resp = string.empty;     string thereq = string.format("tags/{0}", tagname);     var client = new restclient(url);      var request = new restrequest(thereq, method.get);     request.requestformat = dataformat.json;      irestresponse response = client.execute(request);     resp = response.content;     if (!string.isnullorwhitespace(resp))     {         dynamic json = jvalue.parse(resp);         if (null != json.value)         {             result = json.value;         }     }     return result; } 

call server

get http://ame-hp/tags/int32 http/1.1

accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml

user-agent: restsharp/105.2.3.0

host: ame-hp

accept-encoding: gzip, deflate

response server working call:

http/1.1 200 ok

server: internet pack http server

connection: close

set-cookie: sid=f11985564d;expires=fri, 27 jan 2017 07:52:17 gmt;path=/

content-type: application/json

content-length: 133

{"quality":"good","description":"","name":"int32","value":0,"datatype":"int32","controllers":[],"initialvalue":null,"readonly":false}

it's working after 2 calls service answers this

{"code":503,"message":"service unavailable - maximum number of active clients reached."} 

third call server

get http://ame-hp/tags/int32 http/1.1

accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml

user-agent: restsharp/105.2.3.0

host: ame-hp

accept-encoding: gzip, deflate

connection: keep-alive

response server calls , until server restarted

http/1.1 503 service unavailable - maximum number of active clients reached.

server: internet pack http server

connection: keep-alive

content-type: application/json

content-length: 88

{"code":503,"message":"service unavailable - maximum number of active clients reached."}

so assume service has limit of 2 clients. why there exist 2 active clients?

either server or restsharp not closing connection, which?

is there can in restsharp close connection?

the problem was, assumed, server allows 2 clients. on first connection session cookie sent , has used rest of calls.

in restsharp need add 1 line make happen

after creating client (which way need reuse calls). add line:

client.cookiecontainer = new system.net.cookiecontainer(); 

the initialization of client be

client = new restclient(); client.cookiecontainer = new system.net.cookiecontainer(); 

then can use

client.baseurl = new uri(url); 

to set url want call
