Charles 4.1.4


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: Charles requires an add-on in Firefox to autoconfigure Firefox's proxy settings. Charles will automatically prompt you to install the add-on when you run Charles. If the add-on is not automatically installed, you can manually activate Mozilla Firefox Proxy in the Proxy menu. Alternatively, you can download and install the add-on manually.

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
