Subject: Remove Content-Length from chunked encoding
X-Git-Tag: v3.2-beta1~64^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f4e867a148dc82197f02954b753ad30fb0a0f531;p=esp-idf

Remove Content-Length from chunked encoding

Content-Length header should not be included when using chunked encoding.
Some browsers will close the socket after seeing the 0 sized response instead of
reading the chunks.
