SixPack Library

The SixPack library is a high performance, enterprise grade class library aimed at letting developers write the critical parts of a web application right the first time. Main Features
* Almost completely transparent Caching system (Simple, thread safe cache that can be used easily on existing systems, or a more advanced Caching system with prefetching)
* Full, enterprise grade, stored procedure support (including deadlock retries, stored procedure timings)
* Internationalization support (Portugal only, submissions welcome)
* Minimal, high performance logging class supporting filesystem and email
* CAPTCHA generator
* High quality image sizing (can perform scaling and thumbnailing for sites in real time)
* XML over HTTP client (includes support for XSLTs, results as DataTable? or Class)
* Code Generation (programmatically define a class and output source code)
* Small RSA implementation (generate billions of unique short codes for promotions in minutes)
* Text Manipulation (string clipping, sanitization)
* Emailing system (based on CDO and extending it to work with streams)
* Validation (Email address, Credit Cards, ...)
