What Is HTTP Error 206 Partial Content?
Http status code 206 is totally different from other status codes that we see, because it is a successful partial content response.
➯ Meaning of 206 Status Code
The http error 206 Partial Content is a successful https server status response. It simply means that the server has returned only a specific portion of the resource that is being requested and specified by a range header in the user request.
We can take it as, if a user requests only one range of content, then the response you will get in return contains only that specific content range header with the specific resource type.
On the other hand for multi range data, the response you will get contains multipart or byteranges resource format.
➯ When It Is Used in Web Browsing
It used in the following web browsing:
- Very common in streaming media content: It is used to support play, pause, or seek media content without transferring the whole file and to avoid delays in streaming.
- Use in Download managers: It is used by download managers to resume paused downloads by fetching the specific part of data or resource.
- Beneficial in Bandwidth Optimization: It only fetches a specific chunk of data resource. It is best for large files, slow internet connections, or for previews.
Common Causes of 206 Partial Content
Following are the common causes of http status 206 code.
➯ Range Requests in Downloads or Streaming
- User requests partial data or resource through Range header, in that response server responds with that portion of data, that triggers a 206 status code.
- Also, in video or audio playback where players load small data portions as per needed.
➯ Server Configurations and Caching
- The Servers in the backend must support a range of requests, signaled by the “Accept-Ranges: bytes” header.
- If Misconfigurations of resources or proxy behavior can be seen then it might lead to unexpected partial data responses or 206 status code
- Caching can get tricky: some proxy servers try to cache those 206 responses, but screw it up, leading to broken playback or chopped-up files.
Fixing or Handling 206 Responses
Following are the ways to fix or handle 206 error code.
➯ Check Server and Client Requests
- Make sure that the user is sending valid and correct Range header— means correct byte range.
- Double check that the server supports range requests— means Accept-Ranges present and not none.
➯ Ensure Proper File Serving Settings
- On your web server (Apache, etc), it is important to double-check that Accept-Ranges is set to bytes.
- It is important for you to make sure that headers like `Content-Range`, `Content-Length`, and `Accept-Ranges` are all set up accurately.
- Watch out for proxies or load balancers—they’re notorious for mishandling fragmented responses and causing headaches.
