A web server in C language using only the standard libraries and thought it would be useful for you guys if I share the code. The server runs on Linux and includes features like handling HTTP open the file "conf" for reading. tiny.c - a minimal HTTP server that serves static and * dynamic content with the the client */ void cerror(FILE *stream, char *cause, char *errno, char *shortmsg. Check out the mongoose web server, which is an open source project: mongoose. It has very How do I create an online compiler for C language using C# as server language? DNS lookup of remote hosts is an option in logging to files.

These lines of source code is offered as a sample worked example. This is all basic UNIX systems programming and most programmers would come up with something similar, so it cannot be copyrighted as original work. In the real world application though, above model, once default — and still default in Apache AFAIK — is not very efficient, as it forks a new process for every new connection.

Modern web servers i. This is a not-too-big example of non-blocking server engine. Web servers were typically written in C, originally. Looking at these examples inline here, there are a lot of considerations. Web servers can support WebSockets, for example. Are you intending to support those? There are security concerns. There file http server c language a fork bomb issue. A hacker can bring your server to its knees by connecting, keeping the connection open, while connecting again, in an infinite loop.

It will run out of memory and already running programs and daemons will crash or be killed by the OS as it tries to recover. One of the first optimizations in a good implementation would be to pre fork a number of http server child processes. Having those accept connections and deal with connection: If you have a number of processes all in accept at the same time on the same socket, you have a thundering herd kind of file http server c language to deal with. The HTTP protocol itself can be partially implemented and you have a working server.

Do you want the server to support server side business logic? Like running PHP scripts…. Nor does it support chunked output.

Nor a number of other considerations. Logging in a busy server is also a challenge. DNS lookup of remote hosts is an option in logging to files. The time to do that lookup can be seconds. If you are serving the same 20 files over and over again, you could speed things up by caching the entire file contents in RAM.

An even lesser optimization would be to simply mmap the files into application address space and serve that way. Or simply open the files one time and just seek to the beginning each time to serve the contents saves the open call overhead. When dealing with the busiest of servers, memory compares and copies are a huge performance hit.

Those should be optimized. The rest is purely implementation. You interpret the request and file http server c language spit out a response. Some tips:. This is for basic HTTP server. For more complex stuff you can enhance your server with:.

Check out the mongoose web server, which is an open source project: It has very readable code -- mainly because it is small. John Colagioia 's answer is right in a sense: Any functioning web server that is more than a toy is going to have to deal cisco anyconnect 3.1 for mac with the fact that requests can come in simultaneously or effectively simultaneously.

Mongoose gets this right without introducing a lot of complexity. If I remember correctly, it uses pthreads, implements its own thread pool using condition variables to manage synchronization, and uses its thread pool data structure to handle incoming requests. So basically to understand the code you would need to read mpib for nokia condition variables if that is a new topic to you, beyond that there is nothing esoteric in mongoose's code.

Anyway, Mongoose is a real web server that can be embedded in C applications by copying a couple of source files into a codebase.

I have even used it in a product that is sold commercially at a company that didn't believe in writing software in languages besides C no matter how much more sense using other languages made, but that is another story.

If you want to learn how one would go about writing one of these from scratch, examine those couple of source files. Run mongoose in the debugger of your choice and put some breakpoints in there, etc. Thank you for your feedback! Learn how ReSharper helps. You dismissed this ad.

Scale your deployments with a flexible and predictable pricing model. Free for 60 days. It's pretty easy. I've assigned it to classes for a weekend project.

You'll need to know two things: The Berkeley sockets API. Once the server is running, file http server c language simple server is going to: Receive a request from a browser. Parse the HTTP request to figure out what it needs and what supplemental data has been sent. Handle the request. Usually, this means reading the HTML file to send back. Send the HTTP reply. A good web server is harder, though. This is just a skeleton, and knows nothing about security, server-side code, optimizing connections, or anything else.

All of that would go into the "handle the request" part. You have to understand some principles: Some tips: Test your server using the browser to analyze the requests Parse the string into a data structure create your own Request structure for example for easier management This is for basic HTTP idevicemovies ios 8 jailbreak. For more complex stuff you can enhance your server with: I really enjoyed building mine!

You start by reading the HTTP specification, then you implement it. There are some many ways to implement servers, you can do a forking server, a thereading server, a pool of any of those, use lightweight threads, use asyncronous IO, but everything starts with receiving file http server c language request and sending back a response.

You might want to read the thttpd or other mini server source code to get familiar with what are the most important requests the ones they implement and how code is structured Its a huge task to implement a decent HTTP server, but to respond corretly to the most common requests is relatively easy. Few file http server c language of jumping into a mature free software project is that, whenever you are in trouble, The documentation will help you out. Free software projects have extensive documentations on different topics.
