Using Charles Proxy to Modify Server Responses: Map and Breakpoint Techniques

When testing, you may need to force the server to return specific data to cover special cases; Charles proxy provides two methods to modify server responses.

Map feature allows permanent redirection of a request to another remote address or a local file. It includes Map Remote (redirect source URL to another URL) and Map Local (save the response to a file and edit it). The article shows how to configure these settings and provides illustrative screenshots.

Breakpoint feature enables temporary interception and modification of request or response data. By setting breakpoints on a request, you can edit the response (for example, change an ad type) and execute the modified data. The guide walks through selecting breakpoints, editing the response, and executing the changes.

The guide concludes that Charles offers additional useful functions beyond the two described, encouraging readers to explore further.
