Firebase hosting rewrite to an external url - firebase

I am building an app using firebase that needs to load an external webpage under an internal url i.e. when you go to myapp.com/edit it requests the content from someotherapp.com/edit and renders it in the browser without redirecting. I've tried using firebase hosting rewrites, but you can only rewrite to an internal url or a cloud function.

What you're describing cannot be accomplished with rewrites, as those (as you say) can only rewrite to a location on the same server.
A redirect would allow you to redirect to a different server, but that new URL is then sent to the browser.
The only alternative option is to use Cloud Functions or Cloud Run to capture all requests, read from the remote server in that code, and then send that back to the client with a suitable caching interval.

Can my Heroku app call a http endpoint from my GCP backend?

I tried deploying a Heroku web app with my Flask backend (not on Heroku, actually on GCP) and got the following message in my browser's dev console:
Mixed Content: The page at 'https://x.herokuapp.com/' was loaded over
HTTPS, but requested an insecure XMLHttpRequest endpoint
'http://x:5000/endpoint'. This request has been blocked; the content
must be served over HTTPS.
I have little experience with serving and SSL, but the first temptation here would be to find a way to make Heroku okay with using http endpoints. And I'd love to avoid setting up SSL if possible.
What are my options from here?
Thanks!
In the end I realised that by applying my own http domain to the project (rather than using Heroku's domain), I am able to avoid the issue.
Then with http on the frontend, I was able to call http endpoints from my GCP server.

Make available site through http after deploy onto Netlify

I am using two application parts that deployed on: AWS Beanstalk and Netlify.
Java-based part is deployed on AWS and available on http protocol.
Angular based is deployed on Netlify and available on https protocol.
The error occurs when sending a request to AWS:
Mixed Content: The page at 'https://some-url.netlify.com/' was loaded over
HTTPS, but requested an insecure XMLHttpRequest endpoint
'http://some-url.elasticbeanstalk.com/api/getAppSettings'. This request has
been blocked; the content must be served over HTTPS.
I need to do it working for learning purposes only, so try to make Netlify working under Http.
Is it possible to change the protocol to simple http on Netlify?
The adding SSL certificate to Elastic Beanstalk is complicated, unclear and takes too much time
AFAIK, netlify doesn't allow you to access website over HTTP, as they force redirect to HTTPS by default, as mentioned here. But its really easy to have HTTPS on AWS - your elastic beanstalk instances are served with HTTPS by default using an AWS owner certificate, and you can link your custom domain certificate if you have a custom domain, very easily from AWS Certificate Manager.
You can create a netlify.toml file and do some redirect tweaking, as mentioned here.
Creating and configuring a _redirects file in the root of your build folder(or in your public folder if using an SPA like React) might help with this. For your example, the _redirects file would look something like this:
/api/* http://some-url.elasticbeanstalk.com/api/:splat 200
Then rather than call endpoints like this:
fetch(`http://some-url.elasticbeanstalk.com/api/getAppSettings`)
You would need to make your API calls in this format:
fetch(`/api/getAppSettings`) // 'it reads /api/ because of how we configured our _redirects file'

How to enable client redirect from Firebase Functions?

I am transitioning a ReactJS app running on Heroku to be hosted as a static site on Firebase. I am planning to use Firebase Functions to handle logic and drive environment configurations.
A requirement is to support login via 3rd-party Auth0's hosted login page -- the client is redirected to a login page via:
// redirects to auth0's hosted login page
this.auth0.authorize(options);
Because the options argument fed to this method depends on environment-specific configuration it should reside within a Cloud Function (according to my other question that was answered).
There is documentation in Firebase for serving dynamic content from a cloud function but I don't know how to redirect the client from a cloud function.
Is there a way I can do this? Or a more pragmatic solution?

Http redirects to https but it's not support in post request method

i am newer in firebase and i done firebase hosting first time but facing one issue regarding redirection
firebase hosting redirects http:// to https:// directly but i tried it with post request and it's working fine but posted json data is not there to process over on it
This is my firebase.json redirection rule
http://prntscr.com/han083
here is the screenshot of it
This is my code
http://prntscr.com/hamzv9
Without https://
http://prntscr.com/hamybm
With https://
http://prntscr.com/hamyxh
This is because a POST body won't survive a redirect in general. This may be a small bug on Firebase Hosting's part (or perhaps on the part of whatever tool you're using to make the request) -- the HTTP response should be a 301 redirect, which must then be retried with the full POST body by the client.
In general, for any request other than GET you'll need to make sure you properly point at HTTP/HTTPS up front, since redirects don't preserve all request information in most user agents.

Azure App Service won't serve via HTTP

I have an ASP.net MVC app running on Azure App Service ... I've searched for the answer, but have not found it ... my app seems to always force HTTPS redirect, no matter what. All the docs say it should serve content via HTTP by default, but it does not. Most everyone has the opposite problem of needing to redirect HTTP to HTTPS.
I need Azure App Service to do the following:
1) Serve static Default.htm page via HTTP, without redirecting to HTTPS
My app has a custom domain and no SSL for the custom domain. I want the URL http://example.com/Default.htm to serve the static page, not redirect to HTTPS to serve the static page. I will use azurewebsites domain when I want users to be in HTTPS. I want to use my custom domain name to serve a static home page for users arriving at my site.
As far as I can determine, I do not have any app extensions installed (such s https redirect extension), or anything in web.config to force https, or any RequireHTTPS attributes ... can anyone explain why plain old regular boring HTTP doesn't work here?
Thanks
