Hi again! :)

Can you please check if its a bug for case when I have 2 mappings with the same url param but with different values:

first mapping:

{
    "Guid": "e6a48f48-591a-48ff-ae6d-b42fd38321b9",
    "Priority": 1,
    "Request": {
      "Path": {
        "Matchers": [
          {
            "Name": "WildcardMatcher",
            "Pattern": "*/test",
            "IgnoreCase": false
          }
        ]
      },
      "Methods": [
        "GET"
      ],
      "Params": [
        {
          "Name": "abc",
          "Matchers": [
            {
              "Name": "RegexMatcher",
              "Pattern": "[ar]",
              "IgnoreCase": true
            }
          ]
        }
      ]
    },
    "Response": {
      "StatusCode": 200,
      "BodyDestination": "SameAsSource",
      "Body": "hello ar"
    }
  }

second mapping:

{
   "Guid": "7e45210f-fc44-4cf6-9f16-50c17a4611f2",
   "Priority": 1,
   "Request": {
     "Path": {
       "Matchers": [
         {
           "Name": "WildcardMatcher",
           "Pattern": "*/test",
           "IgnoreCase": false
         }
       ]
     },
     "Methods": [
       "GET"
     ],
     "Params": [
       {
         "Name": "abc",
         "Matchers": [
           {
             "Name": "RegexMatcher",
             "Pattern": "[ru]",
             "IgnoreCase": true
           }
         ]
       }
     ]
   },
   "Response": {
     "StatusCode": 200,
     "BodyDestination": "SameAsSource",
     "Body": "hello ru"
   }
 }

For these 2 API calls:

http://localhost:5566/test?abc=ru
http://localhost:5566/test?abc=ar

I get the same following response:

hello ar

Obviously I expect to get "hello ru" for the first one.
I have also noticed that if you change the values of the param to numbers it works correctly for some reason :|

These are my requests:

A regex like [ar] will match any the character a and r.

If you need exact match you need:
^ar$
and
^ru$
