cache-control | cache-control middleware | HTTP library

I suspect the Android emulator might be interfering with you here. I’ve seen issues with it misbehaving, particularly on Windows.

If you'd like to workaround, consider changing your server to use something other than Connection: close to terminate your response body. Perhaps chunked encoding or a content-length header.

It's an authentication issue. Just logout firebase CLI and log in again.

The reason you're seeing a network request is probably because you're using the Cache-Control: no-cache header in your request.

As seen here:

The no-cache response directive indicates that the response can be stored in caches, but the response must be validated with the origin server before each reuse, even when the cache is disconnected from the origin server.

Cache-Control: no-cache

If you want caches to always check for content updates while reusing stored content, no-cache is the directive to use. It does this by requiring caches to revalidate each request with the origin server.

Note that no-cache does not mean "don't cache". no-cache allows caches to store a response but requires them to revalidate it before reuse. If the sense of "don't cache" that you want is actually "don't store", then no-store is the directive to use.

See here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control#response_directives

Here is what a full request for a cached asset looks like on my network tab, when the asset returns 304 Not Modified from the validation request. (from S3) This is in a background: url context.

Dot Points:

• include $request_uri in your proxy pass
• provide a resolver in your proxy location block
• declare an entry for your container in Docker's network stack
• use all lower case in your service name

Below is the configuration file I use to reverse proxy through to a Ubiquiti Unifi container. All my certbot is handled off site so I need not consider that here. If you compare our location blocks, the issue will likely become immediately apparent, but I'll explain for clarity's sake.

What you need to look at is your Proxy Pass directive. This is of course where the magic proxying happens. I notice that you have not been including the $request_uri, so any request nginx receives for bound.example.com/testpage1, it will send a request to the upstream apache server for bound.example.com. Of course if you need to include a port, as I have done here 8443, this is the place to do it also.

If you include this variable, it should resolve your problem.

The following does not answer your question, but I thought I would include it also just as some helpful information.

Also, I just want to note that I have included a resolver. The IP address 127.0.0.11 points to Docker's internal DNS resolver. Chances are you won't need to include this, however I did so myself to ensure I didn't get odd problems. Lastly, I'd just like to recommend that you look into upgrading your SSL settings, to ensure that you are safe from attacks from weaker SSL / TLS versions.

I expect that adding the variable $request_uri to your proxy pass directive is all that is required to get your site working.

The enableCors and { cors: true } options are for the HTTP server (express or fastify). The URL given showing the CORS error came from a socket.io connection. To enable CORS for socket.io you need to use the options in the @WebsocketGateway() decorator, like

I needed a proxy to receive requests from the server. So I used ‍envoy proxy. In this way, nginx received the request from the browser and then sent it to a port (for example 5000). On the other hand, envoy listens to port 5000 and then sends the request to the server running on port 50051.

This is how I designed the tracking of a gRPC connection.

Since 5.0, passenger will "helpfully" add cache-control headers to responses it deems 'cachable'.

In order to stop this, your application should add the header Cache-Control: no-store.

To do this globally in Flask as described here:

Is there a way to do this by keeping it just with javascript and HTML? (or with ASP.NET/C#)

Plain JavaScript and HTML are client side static code. It cannot modify anything stored on the server. You will need a server side application to handle your video uploads, querying, etc. Pretty much all server side languages supports this feature (PHP, ASP, NodeJS, C++, Go, Rust...)

Have you used/implemented something similar (with pictures, documents, etc.)? What technologies did you use?

It's pretty much depends what you want to do. You can go the MVC route to render the HTML code, or going a separate approach by splitting client side and server side code and link them together with an API design.

The Response that you're printing is basically just the initial HTTP info (e.g. status and headers). You'll need to wait for the payload as well using methods depending on what you're expecting:

• bytes/bytes_stream/chunk to get the raw data
• text/text_with_charset to get the data as a string
• json to deserialize the data into a structured type (see the docs for serde_json for more info)

In this case it looks like you're getting a JSON payload so using .json() into a deserializable type sounds like the right way to go, but if your only goal is to print it then .text() is probably the simpler approach.
