    cpp-httplib

    cpp-httplib

    A C++ header-only HTTP/HTTPS server and client library

    A C++11 single-file header-only cross-platform HTTP/HTTPS library. It's extremely easy to setup. Just include the httplib.h file in your code! This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want. SSL support is available with CPPHTTPLIB_OPENSSL_SUPPORT. libssl and libcrypto should be linked. When using SSL, it seems impossible to avoid SIGPIPE in all cases, since on some operating systems, SIGPIPE can only be suppressed on a per-message basis, but there is no way to make the OpenSSL library do so for its internal communications. If your program needs to avoid being terminated on SIGPIPE, the only fully general way might be to set up a signal handler for SIGPIPE to handle or ignore it yourself. cpp-httplib officially supports only the latest Visual Studio. It might work with former versions of Visual Studio, but I can no longer verify it.

    µWebSockets

    µWebSockets

    Compliant web server for the most demanding of applications

    Pushpin

    Pushpin

    Proxy server for adding push to your API

    Pushpin is a proxy server that pins client connections open, making it easy to build real-time API endpoints. Pushpin supports HTTP streaming, HTTP long-polling, and WebSockets. For compatibility with older browsers, it can also translate from SockJS. Clients communicate using your API contract. Pushpin is a server-side implementation detail. An existing real-time API can be migrated to or away from Pushpin without breaking clients. Since Pushpin is a proxy server, the backend can be written in any language. Convenience libraries are available to make integration easy. With Pushpin, API management systems can manage real-time endpoints. Authentication, analytics, etc. work as you'd expect. Pushpin listens on port 7999. Edit the routes file to point traffic to your backend. Make an endpoint on the backend that responds with instructional HTTP headers.

    lixa

    lixa

    LIXA, LIbre XA, is a free and open source XA transaction manager

    LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.
