     It seems like you're having a little trouble separating out the different parts of your question so I'll do my best to help you out with that.

     First and foremost, a common method for understanding communication between two computers is described using what is called the OSI model. This model attempts to distinguish the responsibilities between each protocol in a protocol stack. For example, when you surf a website on your home network the protocol stack is most likely something like

     Ethernet-IPv4-TCP-HTTP-

     This modularization of protocols is used to create a separation of concerns so that developers don't have to "reinvent the wheel" each time they try to get two computers to communicate in some way. If you're trying to write a chat program you don't want to worry about packet loss or internet routing methodologies so you go ahead and take advantage of the lower level protocols that already exist and handle more of the nitty gritty stuff for you.

     When people refer to socket communication these days they're typically using TCP or UDP. These are both known as transport protocols. If you'd like to learn more of the fine details on socket communication I would start with UDP because it's a simpler protocol and then move on to TCP.

     While your web server is aware of some information in the lower level protocols it doesn't really do much with it. Primarily that's all handled by the operating system libraries which eventually hand the web server some raw HTTP data which the web server then begins to process.

     To add another layer, HTTP has nothing to do with the gateway language running behind the scenes. This is fairly obvious due to the fact that the protocol is the same whether the web server is serving CGI perl scripts, PHP, ASP.Net or static HTML files. HTTP simply makes the request and the webserver processes the request accordingly.

     Hopefully this clarifies a few concepts for you and gives you a better idea what you're trying to understand.

   • What does a Terracotta server do when it is used as a backend for EHCache with Hibernate?

     Top Answer

     The idea is it's still significantly faster to contact the terracotta cluster via the terracotta driver and do what's basically a Map lookup, than to acquire a database connection and execute an SQL statement. Even if that does become the application's choke point, overall throughput would be expected to still be significantly higher than a JDBC Connection + SQL choke point. Open connections and open cursors are big resource hogs in the database, an open socket to the terracotta cluster is not!

   • What does SQL Server do with a timed out request?

     Top Answer

     Answered Jan 24, 2020 · 7 votes

     The timeout is enforced by ADO.NET. SQL Server does not know such a thing as a command timeout. The .NET client will send an "attention" TDS command. You can observe this behavior with SQL Profiler because it has an "attention" event.

     When SQL Server receives the cancellation it will cancel the currently running query (just like SSMS does when you press the stop button). It will abort the batch (just like in SSMS). This means that no catch code can run. The connection will stay alive.

     In my experience the transaction will be rolled back immediately. I don't think this is guaranteed though.

     TL;DR: A timeout in ADO.NET behaves the same as if you had pressed stop in SSMS (or called SqlCommand.Cancel).

     Here is reference for this: https://techcommunity.microsoft.com/t5/sql-server-support/how-it-works-attention-attention-or-should-i-say-cancel-the/ba-p/315511

   • What does git do, when I push a local branch that does not exist on remote server?

     Top Answer

     Answered Nov 16, 2013 · 7 votes

     You need to push it like this:

     git branch local_onlygit checkout local_onlygit push origin -

     Then it will create a remote branch and remote origin repository. See more at paragraph "Pushing" here: http://git-scm.com/book/en/Git-Branching-Remote-Branches

     Concerning question what does git do when you 'git push'. According to this article 'git push' is equivalent to 'git push origin master:master'. So it should check your origin/master branch and update it if you have something new in master, regardless of the brunch you are currently on.

If I deploy this back-end to a Netlify server, the Java code does not run, so is it because that Netlify server does not have a JDK to run my Java code?
