<!-- Copyright (C) Nginx, Inc. --> <!DOCTYPE article SYSTEM "../../../../dtd/article.dtd"> <article name="Why nginx doesn’t handle chunked encoding responses from my backend properly?" link="/en/docs/faq/chunked_encoding_from_backend.html" lang="en" rev="2"> <section> <para> <initial>Q:</initial> My backend server appears to send HTTP/1.0 responses using chunked encoding but nginx doesn’t handle it correctly. For instance, I’m using nginx as a frontend to my node.js application and instead of pure JSON from backend, nginx returns something framed in decimal numbers like <programlisting> 47 {"error":"query error","message":"Parameter(s) missing: user,password"} 0 </programlisting> </para> <para> </para> <para> <initial>A:</initial> Your backend violates HTTP specification (see <link url="https://datatracker.ietf.org/doc/html/rfc2616#section-3.6">RFC 2616, "3.6 Transfer Codings"</link>). The "chunked" transfer-codings must not be used with HTTP/1.0. You’d need to either fix your backend application or upgrade to nginx version 1.1.4 and newer, where an additional code was introduced to handle such erratic backend behavior. </para> </section> </article>
