asp.net mvc - call to web api endpoint from same mvc application is timing out -


i have rest service implemented using asp.net web api. reasons needed call 1 of endpoints within same application , report time took response endpoint. added normal mvc controller action below

public class healthmonitoringcontroller : controller {     //     // get: /healthmonitoring/      public contentresult getresponsetime(string id)     {         var startdatetime = datetime.now;         var httpwebrequest = (httpwebrequest) webrequest.create(<<rest endpoint>>);         httpwebrequest.method = webrequestmethods.http.get;         httpwebrequest.accept = "application/json;charset=utf-8";         httpwebrequest.headers.add("accept-language", "en-gb");         httpwebrequest.getresponse();         var duration = (int) datetime.now.subtract(startdatetime).totalmilliseconds;         return content(string.format("response time:{0}", duration.tostring(cultureinfo.invariantculture)));     } }

as can see above, i'm using httpwebrequest class invoke rest endpoint hosted in same website. record time before , after request made , return time.

problem

we have got monitoring tool calls on route recorded response time. monitoring tool calls route every 1 minute. works time , httpwebrequest.getresponse() starts timing out no obvious reason.there nothing in event log , in iis logs

at point if restart application pool, thing start working again time , stops after time.

while above thing not working, if make rest endpoint call myself manually, works. there no issue rest endpoint.

i'm clueless @ point. appreciated.

first off, "health check" same domain pretty irrelevant; , checking latency way trivial. understanding have problems , looking way track issue, use trace log or elmah, not repetitive ping endpoint.

that being said, if want check if api working can instantiate controller , call method directly. test access portion without layering issue potential socket trouble (webrequest/webclient/* libraries). though you're not getting in delay, mentioned, delay useless in context anyways.

var api = new apicontroller(); try {   api.somemethod("param1", "param2");   return content("works"); } catch (exception ex) {   return content("failed: " + ex.message); }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
