I posted this on the talk page for the API. Trying to find an answer.

I did try with 16.5, but still the same error, it is reporting a doubled Content-Length. Where in the code is the header formed for content length? Or is it relying on server?

Doubled Content-Length in HTTP Header

 MediaWiki version: 16.0 – also tried 16.5

PHP version: 5.2.17 (cgi)

MySQL version: 5.0.91-log

URL: www.isogg.org/w/api.php

I am trying to track down a bug in the api which is causing a double content-length in the header. This is causing a lot of issues with a python bot. Here is the report from web-sniffer showing the content of the api.php call from this wiki. All other pages when called, i.e. the Main page, etc. only report 1 content-length. Is the api forcing the headers? Why is doubling only the one?

Status: HTTP/1.1 200 OK

Date: Mon, 30 Jan 2012 14:31:25 GMT

Content-Type: text/html; charset=utf-8 Connection: close

Server: Nginx / Varnish

X-Powered-By: PHP/5.2.17

MediaWiki-API-Error: help

Cache-Control: private

Content-Encoding: gzip

Vary: Accept-Encoding

Content-Length: 16656

Content-Length: 16656

As you can see this is a Nginx server. On an Apache server with 16.0, only one content-length is sent. Could that be the issue and how do I solve it? Thanks.
