Some Android clients disconnect and then retry HTTP request after 15 seconds, even though timeout is larger -

-

I have an Android app that makes an HTTP request to a server that I control. This server relay requests to another server, which I do not control and is currently heavily overloaded, to deal with delays in remote server, I have extended all the timeouts, which I know about.

In my own server, I'm seeing some customers (Android app) seconds and then try the same request again, even if I've set up the connection and are getting bigger than that time Have read the timeout.

Nginx reports in my server that the log in the form of 499, and it always occurs about 15 seconds after the arrival of the request.

Using Sterhurck on my server, I have positively verified that this client is disconnecting (sending an FIN packet) and then retrying the request immediately .

I can not reproduce the issue using my phone. Even if I introduce the server to an artificial delay, my phone respects the timeout I have set. On an recent update, I can see a pattern for problematic phones, but I have not seen any pattern so far, some about the user (phone model, Android version, current connection type) Has started sending basic information.

I was using the first HttpClient on the app, and tried several ways to fix this problem, but time was over and I was trying again. Switched to HttpURL Connection , and I see the same behavior code of code HttpURLConnection is really simple, for example almost literally, for different timeout values Save: 

  InputStream = Faucet; {URL url = Try the new URL ("my.server.com" + paramString); HttpURLConnection conn = (HttpURLConnection) url.openConnection (); Conn.setReadTimeout (180 * 1000); Conn.setConnectTimeout (30 * 1000); Conn.setRequestMethod ("GET"); Conn.setDoInput (true); Conn.connect (); Int response = conn.getResponseCode (); Is = conn.getInputStream (); }   
 I have not mentioned any of this behavior anywhere on the document. Any idea about where this 15-hour time is ending and why my own timeout is not respected?   
 
 
 After seeing myself on this issue, I was able to solve it with the top answer After your request changes will look like the following:  
  ... URL url = new URL ("my.server.com" + paramString); System.setProperty ("http.keepAlive", "Wrong"); HttpURLConnection conn = (HttpURLConnection) url.openConnection (); ...

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from.
