c# - Server not responding for only long requests. Underlying connection was closed. ReadResponse() failed -


i have tried following solutions:

1) increase timeout in client request.

2) increase server executiontimeout in web.config httpruntime tag.

3) have tried using both asmx , wcf services. when server page takes time (code behind), error appears "readresponse() failed: server did not return response request.".

4) change application pool timeouts iis.

5) change iis > website > http response header > set common headers > enable/disable http alive

i using following code test server timeout issue:

    [webmethod]     public string longrequest(int delayseconds)     {         thread.sleep(delayseconds*1000);         return "delayed " + delayseconds + " seconds";     }

we have different servers issue appearing on 1 server.

note! issue appears when request takes more 40 seconds. (this time not specific increases decreases everytime)

issue resolved. figured out server switches configured close longer requests. have used internal ip of server (which accessible our other servers only).

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
