Where does a comma in the HTTP Response Content-Length header come from?
http, servicestack
Solution
It's likely because there were two Content-Length header fields, one with the value "611", the other one "0", and something has merged them into a single field value.
Problem
I am using Fiddler to monitor calls to our ServiceStack API and I am seeing a comma in the Content-Length field. I am only seeing this when I deploy to a specific Windows server. What does that mean? ``` Content-Length: 611,0 ``` The entire response: ``` HTTP/1.1 200 OK Cache-Control: private Content-Length: 611,0 Content-Type: text/plain ETag: 635102562728230000 Server: Microsoft-IIS/8.0 X-Powered-By: ServiceStack/3.955 Win32NT/.NET Access-Control-Allow-Origin: * Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS Access-Control-Allow-Headers: Content-Type X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Wed, 24 Jul 2013 19:03:34 GMT raw data removed but it is 611 characters ``` I did not think commas in the Content-Length field were allowed.
