NOTE:  Currently, the HTTP Server API code only runs successfully when run as x64.
Purpose (from Microsoft's website)
The HTTP Server API enables applications to communicate over HTTP without using Microsoft Internet Information Server (IIS). Applications can register to receive HTTP requests for particular URLs, receive HTTP requests, and send HTTP responses. The HTTP Server API includes SSL support so that applications can exchange data over secure HTTP connections without IIS. It is also designed to work with I/O completion ports.
Description
There have been several times in the past that I wanted to either retrieve information from one of my PCs or execute commands on one of my PCs, whether it was from across the world or sitting on my couch.  Since AutoIt is one of my favorite tools for automating just about anything on my PC, I looked for ways to make to make it happen.  Setting up a full blown IIS server seemed like overkill so I looked for lighter weight solutions.  I though about creating my own AutoIt UDP or TCP server but that just wasn't robust enough,  Then I found Microsoft's HTTP Server API and it looked very promising.  After doing a little research into the APIs, I found that it was flexible & robust enough to handle just about any of the tasks that I required now and in the future.  So a while back I decided to wrap the API functionality that I needed into an AutoIt UDF file to allow me to easily create the functionality I needed at the time.  It has come in very handy over the years.  Of course it wasn't all wrapped up with a nice little bow like it is now.  That only happened when I decided to share it with anyone else who could use it or learn from it.
The example file that I included is a very granular example of the steps required to get a lightweight HTTP Server up and listening for GET requests.  The UDF is a wrapper for the Microsoft APIs.  That means to do anything over and above what I show in the example, one would probably have to have at least a general knowledge of APIs or the ability to figure out which APIs/functions to use, what structures and data is needed to be passed to them, and in what order.  However, the UDF gives a very solid foundation on which to build upon.  Of course, if anyone has questions about the UDF or how to implement any particular functionality, I would probably help to the extent that I could or point you in the right direction so that you can figure out how to implement your own solution.
The APIs included in the UDF are the ones that I needed in the past to do what I needed to do.  If any additional APIs need to be added to the UDF file, please make those suggestions in the related forum topic.

Hi, 
I am new to AutoIT scripting and I am still learning. I am trying to communicate with a Labview application that acts like a server. it basically takes commands from the client. But for some commands, it also send back some data. 
When i am sending commands from my script, i can see that the labview is getting them. But i am not able to get anything back. I tried different code pieces that are available online in the forum.
This is the working piece of code which i been using to send data.
#cs This module is used to establish tcp connection with lab view #ce #include <File.au3> Func SendCmd($cmd) TCPStartup() Local $IpAddress="192.168.10.101" Local $Port="5353" $Labview = TCPConnect($IpAddress,$Port) If @error Then ConsoleWrite('!--> TCPConnect error number ( ' & @error & ' ).' & @CRLF) TCPCloseSocket($Labview) TCPShutdown() Exit EndIf TCPSend($Labview, $cmd & @CRLF) TCPCloseSocket($Labview) TCPShutdown() EndFunc SendCmd("wt42d")  
This is slightly modified code to send and receive data, which is not working. I am not getting any response back
SendCmd("galil") Func SendCmd($cmd) TCPStartup() Local $IpAddress="192.168.10.101" Local $Port="5353" $Labview = TCPConnect($IpAddress,$Port) If @error Then ConsoleWrite('!--> TCPConnect error number ( ' & @error & ' ).' & @CRLF) TCPCloseSocket($Labview) TCPShutdown() Exit EndIf TCPSend($Labview, $cmd & @CRLF) $ip = @IPAddress1 ;create listening socket $Listensocket = TCPListen($ip, $Port) ConsoleWrite("Listening to Socket - " & $Listensocket & @CRLF) If $Listensocket = -1 Then ConsoleWrite("Exiting..." & @CRLF) Exit EndIf ;Accept incoming clients and recieve info While 1 $connectedsocket = TCPAccept($Listensocket) ConsoleWrite("Connecting to Socket - " & $connectedsocket & "Error -" & @error & @CRLF) If $ConnectedSocket >= 0 Then $ip2 = TCPRecv($connectedsocket,1000000) EndIf WEnd TCPCloseSocket($connectedsocket) TCPCloseSocket($Labview) TCPShutdown() EndFunc I am not getting anything back. I am getting the following output in the console
+>Setting Hotkeys...--> Press Ctrl+Alt+Break to Restart or Ctrl+BREAK to Stop. Listening to Socket - 544 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 Connecting to Socket - -1Error -0 its going through that loop forever. i need to force stop it.
But when i open putty and send the same command, i am getting response right away. 
Can someone please help me with that.
Thanks in advance

Hello again to all, I've searched many times in forum and help file to find AES-256-GCM Algorithm for Crypt\Decrypt strings and files but i did not find anything about GCM Algorithm.

Do you have any idea for solving this issue?

I can TCP/IP in AutoIt, hence, make a HTTP deamon. Now, how can I HTTPS to use SSL !??
Well, Apache has this "mod_proxy.so" module that can let me have SSL and what not is in Apache.
All that is needed is to tell Apache what I wanna do by editing httpd.conf .
# Implements a proxy/gateway for Apache. # 1. Open /Applications/XAMPP/etc/httpd.conf # 2. Enable the following Modules by removing the # at the front of the line. # - LoadModule rewrite_module modules/mod_rewrite.so # - LoadModule proxy_module modules/mod_proxy.so # - LoadModule proxy_http_module modules/mod_proxy_http.so # # 3. Copy and Paste below to the bottom of httpd.conf # <IfModule mod_proxy.c> ProxyRequests On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyVia Off ProxyPreserveHost Off ProxyPass /home/ http://127.0.0.1:84/home/ ProxyPassReverse /home/ http://127.0.0.1:84/home/ SetEnv proxy-nokeepalive 1 # ..since we are not using "keep-alive", we are using "close" </IfModule> ...et voila  
I'm using XAMPP ( https://www.apachefriends.org/download.html )
and this is my solution to avoid coding in PHP, as I feel more comfortable coding in AutoIt.
A "muli-thread or concurrency" can be done by forking the socket ( https://www.autoitscript.com/forum/topic/199177-fork-udf-ish/ )
but responses are under 20 ms., so I feel fine with a single thread.
I modified an example ( attached below ), so can try out the concept.
PS: I am not an Apache guru. I just discovered this and it opens a world of possibilities. In my case, I'm thinking of an API to query SQLite 
PS2: I'm not gonna make Poll but do click like if you do

Hello.
I'm french, sorry for my english.
I release my project, a password manager : Password Keeper
First I would like to thanks Guinness and Melba23 for their help, and I'm very sorry for those I forget, please remind me to add you.
Well my program manage and crypt passwords, first I understand if you don't trust me for this kind of sensible software, but I remember you that all the the source files are at your disposal, fell free to explore them.
The login is : admin and you can change it later
How it work ? see Methode de cryptage en BDD.pdf in french
login

 
The main interface
You can obviously add,modify and delete your entry, also you can search with keywords

A password generator is included

I won't update it anymore.
It's a BSD license.
Autoit version : 3.3.14.5
Have a good day.
