HTTPLook
by BinaryAge Software

  HTTPLook gives you the easiest way to test and debug Internet applications that work over HTTP protocol, such as web sites, web services and their clients. It allows you to trace the messages which these applications use for communication. HTTPLook captures (without any modification) data traffic of all Internet applications, including the encrypted ssl traffic of Internet Explorer. HTTPLook parses HTTP messages, separates headers and entities, decodes compressed entities, and saves entities in your file system. Its easy and friendly user interface is designed to make your development experience as comfortable as possible. Sorting, filtering and search features allow you to find an important message quickly. You can also attach notes to interesting messages and save the captured data in your file system in the original format or as a text. Version 1.25 adds a WebDAV, DASL, WebDAV versioning extensions (Delta-V) support and an improved user interface.
