Runtime settings

    Runtime settings allows you to configure the MaxRequestLength and MaxQueryStringLength for your application. Neither of these settings needs to be configured. If nothing is configured reqests and query string can be any size.

    An example of a configuration could look something like:

    "Umbraco": {
      "CMS": {
        "Runtime": {
          "MaxQueryStringLength": 90,
          "MaxRequestLength": 2048

    MaxRequsetLength is specified in kilobytes, so this configuration would limit requests, and therefore uploaded files, to 2 megabytes, and a maximum query string length of 90 characters.
