+        Section is the basic unit of deployment, locking, searching and

+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.

+        Sections cannot be nested.
+        Section groups may be nested.

+      The <configSections> section controls the registration of sections.
+      Section is the basic unit of deployment, locking, searching and
+      containment for configuration settings.

+      Every section belongs to one section group.
+      A section group is a container of logically-related sections.
+
+      Sections cannot be nested.

+/*++
+
+Abstract:
+
+    Main Handler for websocket requests.
+
+    Initiates websocket connection to backend.
+    Uses WinHttp API's for backend connections,
+    and IIS Websocket API's for sending/receiving
+    websocket traffic.
+
+    Transfers data between the two IO endpoints.
+
+-----------------
+Read Loop Design
+-----------------
+When a read IO completes successfully on any endpoints, Asp.Net Core Module doesn't
+immediately issue the next read. The next read is initiated only after
+the read data is sent to the other endpoint. As soon as this send completes,
+we initiate the next IO. It should be noted that the send complete merely
+indicates the API completion from HTTP, and not necessarily over the network.
+
+This prevents the need for data buffering at the Asp.Net Core Module level.

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+// Furthermore, the allocator will not be used for arrays of objects
+// (override operator new[] and operator delete[]), but this is a
+// harder problem since the allocator works with one fixed size.

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without

+/*++
+
+Abstract:
+
+    Main Handler for websocket requests.
+
+    Initiates websocket connection to backend.
+    Uses WinHttp API's for backend connections,
+    and IIS Websocket API's for sending/receiving
+    websocket traffic.
+
+    Transfers data between the two IO endpoints.
+
+-----------------
+Read Loop Design
+-----------------
+When a read IO completes successfully on any endpoints, Asp.Net Core Module doesn't
+immediately issue the next read. The next read is initiated only after
+the read data is sent to the other endpoint. As soon as this send completes,
+we initiate the next IO. It should be noted that the send complete merely
+indicates the API completion from HTTP, and not necessarily over the network.
+
+This prevents the need for data buffering at the Asp.Net Core Module level.

+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and

+
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+
+        Sections cannot be nested.
+        Section groups may be nested.

+
+        The recommended way to unlock sections is by using a location tag:

+  <!--
+    Microsoft ResX Schema
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+
+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and
+        containment for configuration settings.
+
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+
+        Sections cannot be nested.
+        Section groups may be nested.
+
+        <section
+            name=""  [Required, Collection Key] [XML name of the section]
+            allowDefinition="Everywhere" [MachineOnly|MachineToApplication|AppHostOnly|Everywhere] [Level where it can be set]
+            overrideModeDefault="Allow"  [Allow|Deny] [Default delegation mode]
+            allowLocation="true"  [true|false] [Allowed in location tags]
+        />
+
+        The recommended way to unlock sections is by using a location tag:
