Setting the maximum buffer size for response content

Configures the maximum number of bytes to buffer for the response content of a single request.

HttpRequestBuilder.Get("https://furion.net/")    .SetMaxResponseContentBufferSize(10 * 1024);    // Set to 10KB

If the Content-Length of the response content exceeds the configured MaxResponseContentBufferSize limit (for example, a limit of 10240 bytes), an HttpRequestException is thrown. The message of that exception is: Cannot write more bytes to the buffer than the configured maximum buffer size: '10240'..

Notes on the maximum buffer size of HttpClient response content

When setting the maximum number of bytes to buffer for response content on HttpClient, make sure the maximum buffer size for the response content of a single request does not exceed the maximum buffer size configured for the HttpClient response content. For example, if the maximum buffer size of the HttpClient response content is set to 5120 bytes while the maximum buffer size of a single request is set to 10240 bytes, then the single request will still trigger an HttpRequestException when it exceeds 5120 bytes. The sample code is as follows:

services.AddHttpClient(string.Empty, client =>{    client.MaxResponseContentBufferSize = 5 * 1024;});

Therefore, if a single request needs a larger maximum buffer size for its response content, make sure the maximum buffer size of the HttpClient response content is set correspondingly larger.
