WebView2ResponseHeaders class

The HTTP-response-header collection for a web-resource response. Reached through WebView2Response.Headers inside a WebResourceRequested event handler.

The collection is enumerable — For Each yields one WebView2Header per entry. Unlike the request side, AppendHeader appends additional values rather than overwriting the existing one, matching HTTP’s allowance of repeated response headers (e.g. multiple Set-Cookie).

Private Sub WebView21_WebResourceRequested( _
        ByVal Request As WebView2Request, _
        ByVal Response As WebView2Response)

    Response.StatusCode = 200
    Response.ReasonPhrase = "OK"
    Response.Headers.AppendHeader "Content-Type", "text/plain; charset=utf-8"
    Response.ContentUTF8 = "Hello from twinBASIC."
End Sub

Methods

AppendHeader

Appends a header — adds it to the collection even if an entry with the same name already exists. Repeated headers are legal in HTTP responses.

Syntax: object.AppendHeader name, value

name

required A String header name.

value

required A String header value.

Contains

Indicates whether a header with the given name is present in the collection.

Syntax: object.Contains ( name ) As Boolean

name

required A String header name.

GetHeader

Returns the value of the named header — when there are several, the first.

Syntax: object.GetHeader ( name ) As String

name

required A String header name.

GetHeaders

Returns a WebView2HeadersCollection iterator restricted to the headers that match name.

Syntax: object.GetHeaders ( name ) As WebView2HeadersCollection

name

required A String header name.

Iteration

A For Each loop produces every header in turn:

Dim h As WebView2Header
For Each h In Response.Headers
    Debug.Print h.Name & ": " & h.Value
Next

See WebView2HeadersCollection for the iteration object.
