ASP.NET 

Rebex ZIP can be used within an ASP.NET web page. However, you have to keep in mind specific features of the ASP.NET platform (it is stateless, multithreaded, it may be limited by MediumTrust security level...).

You can get inspired by the ASP.NET ZIP Archive Browser sample.

Further info on using Rebex components in web environment can be found in How to use Rebex SFTP or FTP/SSL in ASP.NET knowledge base article. The article discusses SFTP and FTP/SSL, but implications for Rebex ZIP are the same.
