JFileUpload is a Java applet that allows you to upload files and folders to any Web or FTP server. It can be integrated into any application. The server-side technology could be JSP/Servlet, PHP, Coldfusion, CGI, or Microsoft ASP. The front-end provides an upload progress bar, a cancel button, and drag and drop support.
PyAMF provides Action Message Format (AMF) support for Python that is compatible with the Adobe Flash Player. It includes integration with Python Web frameworks like Django, Pylons, Twisted, SQLAlchemy, and more. The Adobe Integrated Runtime and Adobe Flash Player use AMF to communicate between an application and a remote server. AMF encodes remote procedure calls (RPC) into a compact binary representation that can be transferred over HTTP/HTTPS or the RTMP/RTMPS protocol. Objects and data values are serialized into this binary format, which increases performance, allowing applications to load data up to 10 times faster than with text-based formats such as XML or SOAP.
RayHttp is a PHP class that provides an HTTP client for sending requests to Web servers. It can configure and send HTTP GET and POST requests using the Curl extension or PHP file access functions. When using the Curl extension, all Curl options may be set changing a class array variable.
phpWebHacks is an advanced HTTP client written in PHP, a utility for HTTP scripting. It simulates a real Web browser, but you use it with lines of code rather than a mouse and keyboard. It uses pure PHP; no Curl or other fancy dependencies are needed. You can build scripts in minutes: a GMail/Yahoo/MSN contacts grabber, a YouTube video downloader, an HTTP mailer, and many more.
sshh is a set of two daemons that allows you to maintain a TCP connection if all you have available is an HTTP proxy. It is similar in functionality to httptunnel, but has a few more features. Once you have it set up, sshh will allow you to make connections forward through the proxy or backwards through it, so you can open connections in either direction.
