The Request Viewer is where you can view the details of any recorded request or response.

When you click on a request in either the structure view or sequence view, the information for it is loaded in the viewer.

The viewer is divided into several tabs:

• General - for general information and statistics
• Request - for request headers and body
• Response - for response headers and body
• Summary - for a summary of all related events
• Notes - for notes that you can make to help with big debugging missions

The General tab displays general information about the request, this includes:

• URL - the full URL
• HTTP Status - the HTTP status code for HTTP requests
• Request Start Time - the timestamp of when the first byte of the request is received by Charles
• Response Start Time - the timestamp of when the first byte of the response is received by Charles
• Response End Time - the timestamp of when the last byte of the response is received by Charles
• Client Address - the address of the client making the request to Charles
• Remote Address - the address of the remote machine, the target of the request
• Request Size - the size of the request body (if there is one, ie. for POST)
• Response Size - the size of the response body
• Duration - the duration of the event from request start time to response end time
• Latency - the time between the request start time and the response start time, that is the time it takes from making the request to starting to receive the response
• Download Speed - the speed at which the response is downloaded, that is the response size over the time to download the response (response end time - response start time)
• Mime-Type - the HTTP mime-type as found in the Content-Type header
