I am a new back-end developer, I got a request that making a back-end can run on Apache server but I do not know what type of programming language can develop a back-end can run on that kind of server. I tried many queries about this topic but non result.Please help me!
I am planning to choose Golang for this project but I am confusing about it.
Unfortunately, Apache's module page doesn't list third party modules. However, there is a Wikipedia page that lists third party modules.
mod_aspdotnet - serves ASP.NET content using the Microsoft's ASP.NET hosting and .NET runtime
mod_cgi - executes CGI scripts
mod_cgid - executes CGI scripts using an external CGI daemon
mod_fcgid - high performance alternative to mod_cgi or mod_cgid
mod_fastcgi - enables FastCGI
mod_go - module for deploying web applications in Go
mod_jk - handles the communication between Tomcat and Apache
mod_lisp - for writing web applications in lisp
mod_lua - extends Apache with scripts written in Lua
mod_mono - provides ASP.NET support
mod_parrot - exposes the Apache API to a Parrot virtual machine interpreter
mod_perl - gives you a persistent Perl interpreter embedded in your web server
mod_php - enables usage of PHP within Apache
mod_prolog - embeds the Prolog interpreter within the server
mod_python - embeds the Python interpreter within the server
mod_r - embeds the R interpreter inside Apache
mod_ruby - embeds a Ruby interpreter in Apache
mod_suphp - executes PHP scripts with the permissions of their owners (unmaintained)
mod_wsgi - implements a WSGI compliant interface for hosting Python based web applications
It is likely that there are other modules that are unlisted because mod_go, mod_lua, and mod_prolog weren't included in the Wikipedia page. I found them by searching for "apache mod_golang", "apache mod_lua", and "apache mod_prolog". Also, a number of them no longer appear to be maintained.
We can say there are many languages which supports deployment on Apache web server. But here if you need a bunch of languages which runs natively on apache web server
Then you can visit this site https://en.m.wikipedia.org/wiki/Apache_HTTP_Server
And explore features tab in it.
And you can see last 7 option in it which says
"Embedded Perl, PHP and Lua scripting"

I've started working with delphi quite some while ago but I would say I'm still a newbie in all this.
So basically I tried creating REST Server, which can validate license keys. I got in working with Indy, but one thing bothers me. The GUI. The Server shouldn't have any kind of gui so it can work on any OS (Win, Linux, etc). Is there a way to make a REST Server without any GUI/FMX/VCL?
BTW: Working in Delphi 10.2.3 Professional.
Any advice is appreciated.
EDIT: I forgot to mention one thing: the server is supposed to run on an independent Data Center away from any user.
You can create the WebServer as a Windows Service.
You can use DelphiMVCFramework or any other Framework to create it.
With DMVC you can create console application, Windows Service, Linux daemon, Apache module (Windows and Linux) and IIS ISAPI (Windows).
With Intraweb you can also create Services.
Take a look at our mORMot Open Source REST framework, which works on Delphi but also on FPC/Lazarus.
FPC support ensures that you can target Linux with this free compiler. No need to upgrade to a newer version of Delphi Architect, which supports Linux, and is very pricey - and less stable (to my knowledge) since Linux support is quite new.
As you requested, the mORMot REST server has no UI part. You define your services as interface and class - like you do e.g. with DotNet - and you will have full JSON/REST support generated.
mORMot is used on production since years for very high performance and stability, hosted on both Windows and Linux. A version 2 is on its way, which would be even easier to use for new projects.
And you can create a Windows service or Linux daemon without using any third party framework. Delphi include everything you need. However, it is possible that third party framework will facilitate your programming. Don't forget you'll have to learn those third party framework.

In both cases, you can use the sample code you've found that make use of TIdTCPServer.
I already know enough about the Apache HTTP Server, but what are the other most popular web server types? And where I can get the programs and documentation on how to set them up?
that depends on which OS you are using.
in Linux the apache http in all his forms ( tomcat/catalina/httpd ) is the most common , afterwards the nginx is also quite common.
I am less familiar with windows but I think IIS is the most common in windows.
I am new to the programming world and started with Perl couple of days back. I tried developing a web application using Perl. Initially followed some tutorial and learned how to write simple CGI scripts using Perl and deployed it using Apache2 httpd server. After getting to know about the Perl Dancer it was much easier to develop a web application using the framework.As both serve the same purpose I want to know weather Dancer is a replacement to the Apache httpd server or dancer internally uses apache to start a server. As dancer is just a web application framework how internally it is managing to handle the server request and responses.
Can anybody post a link where I can read and get to know about how the webserver works?
Dancer has a PSGI interface.
PSGI is similar to CGI in that it allows a web server to communicate with the Perl application, but it is more efficient (it keeps the application running all the time so it doesn't need to load everything from scratch for each request) and has more features (e.g. the ability to use Plack middleware).
Dancer comes with a script to run a simple web server (which is not Apache) for development purposes.
It is expected that you'll use a more powerful web server (such as Apache HTTPD) in production.
I'm building a web app with Backbone.js (I'm not tied to Backbone yet though). I need a back-end framework only for persistence to a database via a RESTful API. However, I also need to able to deploy it as a 'desktop' app for off-line use, i.e. running a local server and launching a browser window, but I don't want users to have to start a server from the command line to run the application.
I can use SQLite as a database since it's only a single user application, it's just the framework that I'm stuck on. I have looked at the following:
Rails and Django: Default web servers are too flimsy, requires Ruby/Python and runs from the command line. I'm aware of the Bitnami stacks but at 99mb it's too big of a dependency and not exactly hidden from the user.
Sproutcore: Run from command line, also too bulky.
Pyjamas Desktop - Depends on MSHTML which I suspect limits my ability to use HTML5 features.
I'm leaning towards creating a Java app that starts a Scala/Lift server instance and opens a web browser, then sits in the system tray (kind of like WAMP). Is anyone familiar with a tool or framework built for user-friendly deployment as a standalone desktop app?
I do not know if PHP is an option for you? Then I would recommend phpdock.
web2py has a standalone deploy-to-desktop feature with no dependency on Python: http://web2py.com/books/default/chapter/29/14#How-to-distribute-your-applications-as-binaries
As Eydun said, phpdock is an option but it's commercially licensed .
I settled on using Java/Spring/H2/Hibernate/Jetty. I find that Jetty serves requests VERY quickly so the application looks real-time when launched in a browser. There is a tutorial on embedding the Jetty server here. I imagine it's quite trivial to build a GUI that launches the server and a browser.
Another Java option is to use the Play Framework, which may be more at home to those coming from a Django/Rails background. However, the documentation for "creating a standalone version of your application" for Play 2.0+ indicates that they have ditched using Java EE containers (Tomcat/Jetty) and WAR files in favor of running the JARs with the bundled copy of JBoss Netty, so it may take a bit of work to get it running the way you want it.
I would recommend the Play Framework approach if you're OK with using/learning Scala.
Is an application server something like an additional layer of application servicing above a web server?
Does an application server always have a web server as its core?
What is the difference?
No,Application server does not contain web server...
Read following articles...
http://www.answers.com/topic/application-server
http://download.oracle.com/docs/cd/E19159-01/819-3671/ablat/index.html
Basically:
After the Web exploded in the mid-1990s, application servers became Web based.
Also following shows the difference between web server, web container and application server...
Difference between a Web Server, Web Container, and an Application Server
A Web Server is a server capable of receiving HTTP requests, interpreting them, processing the corresponding HTTP Responses and sending them to the appropriate clients (Web Browsers). Example: Apache Web Server. Read more about Web Servers and their working>>
A Web Container is a J2EE compliant implementation which provides an environment for the Servlets and JSPs to run. Putting it differently we can say that a Web Container is combination of a Servlet Engine and a JSP Engine. If an HTTP Request refers to a Web Component (typically a Servlet or a JSP) then the request is forwarded to the Web Container and the result of the request is sent back to Web Server, which uses that result to prepare the HTTP Response for the particular HTTP Request. Example: Tomcat is a typical Web Container. A typical setup would be to have Apache HTTP Server as the Web Server and Tomcat as the Web Container.
An Application Server is a complete server which provides an environment for running the business components (EJBs, ADF BCs, etc.) in addition to providing the capabilities of a Web Container as well as of a Web Server. Example: Bea WebLogic, IBM WebSphere, Oracle
Application Server, etc.
Actually, with the explosion of the web, and in particular "web services", all modern App Servers can also function as Web Servers. For example, the current version of Tomcat includes built-in Web Server functionality so you no longer must run a separate Apache HTTP server. In the past, running separate dedicated Web Servers such as Apache was preferable since the App Server was optimized for App Server rather than for Web Server, processing; but the performance of App Servers as Web Servers has improved such that any remaining performance difference is irrelevant - and certainly does not justify the expense of running separate servers.
Today, the major difference is that an App Server is designed to support programming languages such as Java or, on the .net platform, C# - as well as to provide an underlying infrastructure that includes automatic fault-tolerance, session mgmt, transaction mgmt, multi-threading - and everything else required to build scalable enterprise applications. Current Web Servers are designed to support languages such as Ruby, PHP, Python and Perl - and lack the built-in infrastructure of an App Server.
However, the distinction between App Servers and Web Servers is blurring and will continue to do so as "Web Services" becomes ever-more popular and languages such as Ruby mature and therefore require Web Servers to provide much of the same underlying infrastructure as today's App Servers. In the end, the primary difference will be (not yet): if you want to develop the back-end (cloud) layer of your application employing Java or C#, employ an App Server; if you want to develop your application employing Ruby, PHP or Perl, employ a Web Server.
While a Web server mainly deals with
sending HTML for display in a Web
browser, an application server
provides access to business logic for
use by client application programs.
