How to detect end of Http request?

Question

I am creating a Http request parser. I am getting data in chunks (byte array) and parsing it simultaneously. I want to know the condition of detecting end of http request. The request may or may not contain message body.

Thanks

Three different ways:

• content-length header (number of bytes following the headers)

• chunked encoding (content length unknown at start of request, chunked encoding will indicate when the end is reached)

• connection closed by server (http "0.9")
