I want to add some constant headers for my Yii REST API whenever it return 200 status code or 500 in any format: XML, HTML, JSON, so every response will contain their
Is it possible in Yii send these headers anyway?

I am trying to POST with URL encoded data. Based on the web server logs, I am not actually sending any data from Twilio (request size is always 131 bytes, no matter what I type in the Studio widget box).
What does a working form body look like? Do I need to encode it myself? How do I escape an "=" that is not part of the key-value structure?
When making an HTTP request with the widget, when it is set to make Form URL encoded requests you can set the HTTP parameter keys and values which will automatically encode the values. There are known as URL parameter as the encoding is Form URL encoding. The parameters are encoded as if they were in a URL, but they are sent as the POST body.
I am looking for an appropriate HTTP status code that tells the receiver that just the meta-data is being sent, not the complete data.
For example, say you do an HTTP GET:
GET /foo?meta_data_only=yes
the server won't look up the complete data, just send some metadata back about the endpoint, for example. Is there an HTTP status code for the response that can represent this? I would guess it's in the 200s or 300s somewhere?
Since your metadata is being returned in the headers, I would send a status code of 204 No Content.
https://httpstatuses.com/204
The server has successfully fulfilled the request and that there is no
additional content to send in the response payload body.
Metadata in
the response header fields refer to the target resource and its
selected representation after the requested action was applied.
This sounds exactly like what you’re looking for: a successful response that contains no body, and metadata in the headers that provide additional about the resource.
Another thing worth noting is that it’s common practice to use the HTTP verb HEAD when you only want metadata. HEAD is very similar to GET, except that it specifies that you do not want a body back. For example if you do a HEAD to an image url, you will get a 204 No Content response and some metadata about the file such as Content-Type, Content-Size, maybe ETag, but you won’t be sent all of the file data. A lot of web servers (such as Nginx) support this behavior out of the box for static files. I would recommend that you stop using your querystring parameter, and instead implement HEAD versions of your endpoints. That would make the intention even more clear and intuitive.
Supposing I was to stream a large response to a browser, or other HTTP client; is there a way for the server to return an HTTP 500 error page mid-way through the download?
For example, I may be serving a very large HTML page, or perhaps displaying a large JPEG file in its own tab, and the data-source is terminated prematurely. At this point I want to show my standard HTTP 500 error page.
If it helps, I can use Content-Transfer-Encoding: chunked, or even other hackish HTTP headers to make this work.
Is it possible to override a download result on the HTTP level?
I know one could add a JavaScript alert if the response were in HTML format, but I'm just wondering if I can override / restart the response on the HTTP level instead?
I was trying to read the value of the Content-Type header in a custom delegating handler in ASP.NET Web API. When I queried the request.Headers collection, the header value wasn't in there. However, it was contained in request.Content.Headers. Other non-standard headers (such as Content-Test) starting with Content- were available in request.Headers only; Content-Length, on the other hand, could only be found within request.Content.Headers, just like Content-Type.
Is it correct to assume that Web API is putting all known content headers into the request.Content.Headers collection while putting all other headers into request.Headers?
That's how the HttpClient was designed in the first place. Requests and responses are separate from the actual content hence content related cookies go into the HttpContent.Headers rather than HttpRequestMessage.Headers. Keeping the content headers with the content is a good way of separating the concerns, on the other hand, getting to the content headers is a bit more cumbersome.
See what I'm trynig to do is on a post request made collect the http headers and then add them to app.Request.Headers.Add().
In my application basically another post request overides certain post requests that I make.
On each request to my server there is a redirection to another server which adds some headers over my original post request
I need some way of saying maybe ok add these headers but then execute my post request with its headers after
