- requestUriString
- String
A URI string that identifies the Internet resource.
Returns
An HttpWebRequest instance for the specific URI string.
- Attributes
Exceptions
The request scheme specified in requestUriString is the http or https scheme.
requestUriString is null.
The caller does not have WebPermissionAttribute permission to connect to the requested URI or a URI that the request is redirected to.
The URI specified in requestUriString is not a valid URI.
Remarks
The CreateHttp(String) method returns an instance of the HttpWebRequest class for the requestUriString.
When a URI that begins with http:// or https:// is passed in the requestUriString parameter, a HttpWebRequest is returned by CreateHttp(String). Any other scheme will throw a NotSupportedException.
The CreateHttp(String) method uses the requestUriString parameter to create a Uri instance that it passes to the new HttpWebRequest. If the method is successful, the AllowReadStreamBuffering property on the returned HttpWebRequest instance is set to false.
.NET includes support for the http:// and https:// URI schemes. Custom WebRequest descendants to handle other requests are registered with the RegisterPrefix method. The Create(String) method can be used to create a descendant of the WebRequest class for other schemes.
