Hi,
Is there any way to modify a response when running a server in proxy mode?
For example I got the following the response in proxy mode, and I need to change part of the body of the response before returning it:

{
	"Guid": "f43a630e-90a9-4b39-aa92-85820f84f4a7",
	"Title": "",
	"Request": {
		"Path": {
			"Matchers": [
				{
					"Name": "WildcardMatcher",
					"Pattern": "/Abc",
					"IgnoreCase": false
				}
			]
		},
		"Methods": [
			"GET"
		]
	},
	"Response": {
		"StatusCode": 200,
		"Body": "{\"revision\":\"2023-01-18T17:56:59.5680265Z\",\"json\":\"{\\\"URL\\\":\\\"https://www.google.com/abc\\\"}\"}",
		"Headers": {
			"Content-Type": "application/json; charset=utf-8"
		}
	}
}

and I want to change the url in the response body to:

"https://localhost:8080/abc"

@avrahamshurin
I don't think so, but I'll check this.

@avrahamshurin
This can be done using response templating :
