title: Send http request in JMeter without escaping characters
body: <p>I am sending the following data using a HTTP request:</p>
  
  <pre><code>{
  "id": "a",
  "jsonrpc": "2.0",
  "method": "addJsonEvent",
  "params": {
      "common_fields": {
          "source_hwid": "${HWID}",
          "api_key": "${custid}"
      },
      "data": ["{ \"parent_process_path\": \"C:\\\\disk2\\\\process.exe\", \"command_line\": \"\\\"C:\\\\Windows\\\\Microsoft.NET\\\\Framework\\\\v4.0.30319\\\\ngen.exe\\\" uninstall \\\"C:\\\\Windows\\\\assembly\\\\NativeImages_v4.0.30319_32\\\\Microsoft.W2d29a719#\\\\fdb201638092fc8d1310350e099eba45\\\\Microsoft.Windows.DSC.CoreConfProviders.ni.dll\\\" /noroot /LegacyServiceBehavior\", \"api_key\": \"${custid}\" }"]
  }}
  </code></pre>
  
  <p>Looking at the <code>View Results Tree</code> I see that the data sent is the following:</p>
  
  <pre><code>{
  "id": "a",
  "jsonrpc": "2.0",
  "method": "addJsonEvent",
  "params": {
      "common_fields": {
          "source_hwid": "560ade69-808e-18a4-7d2a-123-123456000001",
          "api_key": "5a9fb2311da1972e6c8b4567"
      },
      "data": ["{ \"parent_process_path\": \"C:\\disk2\\process.exe\", \"command_line\": \"\\"C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\ngen.exe\\" uninstall \\"C:\\Windows\\assembly\\NativeImages_v4.0.30319_32\\Microsoft.W2d29a719#\\fdb201638092fc8d1310350e099eba45\\Microsoft.Windows.DSC.CoreConfProviders.ni.dll\\" /noroot /LegacyServiceBehavior\", \"api_key\": \"5a9fb2311da1972e6c8b4567\" }"]
  }}
  </code></pre>
  
  <p>The actual data sent is no longer a valid JSON. </p>
  
  <p>Is there any way to sent the data as is, without escaping those characters ?</p>
