Charles 4.2.8


Charles Icon


Charles is an HTTP proxy/HTTP monitor/Reverse Proxy that makes debugging quick, reliable and advanced; saving you time and frustration. It enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

Charles will autoconfigure your browser's proxy settings on the following browsers:
  • Windows system proxy settings (includes Internet Explorer and most other applications)
  • Mac OS X system proxy settings (includes Safari and most other applications)
  • Mozilla Firefox (on all platforms)

Note: Firefox no longer requires an add-on to work with Charles. Instead configure Firefox to use your system proxy settings..

Key Features:
  • SSL Proxying - view SSL requests and responses in plain text
  • Bandwidth Throttling to simulate slower Internet connections including latency
  • AJAX debugging - view XML and JSON requests and responses as a tree or as text
  • AMF - view the contents of Flash Remoting / Flex Remoting messages as a tree
  • Repeat requests to test back-end changes
  • Edit requests to test different inputs
  • Breakpoints to intercept and edit requests or responses
  • Validate recorded HTML, CSS and RSS/atom responses using the W3C validator
