I get the following HTTP response headers in a particular response. All looks okay. However I have noticed that the content-length appears twice...
Content-Length: 2424 ntCoent-Length: 2424
Is there a particular reason why the content-length is returned a second time as ntCoent-Length?

The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.
To manually pass the Content-Length header, you need to add the Content-Length: [length] and Content-Type: [mime type] headers to your request, which describe the size and type of data in the body of the POST request.
Description. The Content-Length is optional in an HTTP request. For a GET or DELETE the length must be zero. For POST, if Content-Length is specified and it does not match the length of the message-line, the message is either truncated, or padded with nulls to the specified length.
The comments in https://basildoncoder.com/blog/turbocharging-net-webservice-clients.html say the jumbled ntCoent-Length header contains the uncompressed size of the response.
You should see the Content-Length is smaller than ntCoent-Length in cases where Content-Encoding:gzip or similar

FYI, HTTP headers from some clients have characters randomly replaced gives other examples of letter transposition in http headers.
