Is there a response content filter in litespeed web server? - litespeed

I being new in Litespeed, I used to use the Nginx web server, but now I have a business that I must use Litespeed. And my problem is, is there any content response filter in Litespeed? In Nginx, I used to use the sub_filter module.
I've searched in Google about this, but the solution not found

Forward requests from example.com:8000 (old REST API) to api.example.com (new REST API) on AWS

So I have this problem and I am a bit confused on where to start. I have a Django REST API currently running on a VPS (with apache) and start with djangos runserver command (I know, I know, not the best way) so it is currently accessed via http://example.com:8000/api.
I am now moving to AWS and using Elastic Beanstalk to run my newly created Django REST API. I want to keep the domain something like example.com/api or api.example.com. Now this should be fine for me to set up but the problem I now have is I want to forward all old requests using the old API to the new API. What is the best way to do this?
Any help will be appreciated! :)
There are two ways to do this.
Rewrite
Redirect
Rewrite:
With rewrite you read the contents using the old api and serve on the same request.
Redirect:
With redirect you send a 302 with the redirect location to your new API url.
Any request to http://example.com:8000/api/something will be responded with a http status code 302 and location as http://example.com/api/something or http://api.example.com/something
If you do not wish you to use the old API, then it is better to redirect to the new destination.
If changing the URL on the client side is possible, then you can abondon mantaining the old endpoint or any of these process.
Hope it helps.

Browserify + WebStorm debug breaks routing in React-Router v4 BrowserRouter

I am writing a single page app with React for educational purposes. My React-Router v4 BrowserRouter handles client side routing correctly on CodeSandbox but not locally. In this case, the local server is the webstorm built-in devserver. HashRouter works locally but BrowserRouter does not.
Functioning properly: https://codesandbox.io/s/j71nwp9469
You are likely serving your app on the built-in webserver (localhost:63342), right? Internal web server returns 404 when using 'absolute' URLs (the ones starting with slash) as it serves files from localhost:port/project_name and not from localhost:port. That's why you have to make sure to change all URLs from absolute to the relative ones.
There is no way to set up the internal webserver to use project root as server document root. But you can configure it to use URLs like http://<host name>:<port> where the 'host name' is a name specified in hosts file, like 127.0.0.1 myhostName. See https://youtrack.jetbrains.com/issue/WEB-8988#comment=27-577559.
The solution was to understand how push state routing and the history API works. It is necessary to proxy requests through the index page when serving Single Page Applications that utilize the HTML5 History API.
The Webstorm dev server is not expected to include this feature, therefore the mention of Webstorm in this thread was a mistake.
There are multiple libraries of < 20 lines which do this for us, or it can easily be hand coded.

Loading http content on https domain

We have created a website which is served right now on Heroku. This website has a search bar in the navbar and I wanted to use Freefind search service for the backend. The search result I receive from it are all over the HTTP server and Heroku server will not load it.
I want them to work fine just as they work on localhost. What can I do?
The app is Django based and I tried to google custom search but it didn't work for me.
You can't load most HTTP content on HTTPS domains. Loading HTTP images is fine, but is still discouraged. This is called mixed content blocking, which is a browser's feature.
The only thing you can do is to find out if freefind's search service supports HTTPS. You can try changing the URL to https://search.freefind.com/... and see if it works. Or contact freefind and ask them if they support HTTPS. If they don't support HTTPS, you have to find a different company's search service.

nginx, django and url mapping

The admins where I work have a url http://company.com/app, public facing. They use apache http server. The sysadmins have http://company.com/app pointing to http://internal_ip_address:8080. I have nginx sitting on http://internal_ip:address listening on 8080. I am trying to get nginx to take requests coming into internal_ip_address, route the requests to localhost:9000 which is a django app. Once django is done with the request the resulting page renders with appropriate public facing url (e.g. http://company.com/app . . .) Thanks for any help!
Thanks to all those that tried to help. After spending a notable amount of time on the issue I determined that it was a http server config issue on a server managed elsewhere.

ARR/IIS 502 Errors When Returning JSON

Here's our current setup: (assume everything is using https)
Web Services server running a simple asp.NET Web API 2 application that returns only JSON. (api.example.com/controller/blah)
Primary web server that's going to contain scripts that use AJAX to access resources through our Web Services.
My end goal is to not have to deal with CORS because IE is being problematic. (I've tried several jQuery plugins to resolve problems with XDomainRequest, on top of our domain security settings causing IE to deny the requests anyways... it's just a mess.)
Route requests from www.example.com/api/* to api.example.com/* and return the JSON response.
However, when I've attempted to set this up with IIS + URL Rewrite + Application Request Routing (ARR) I get the following message when attempting to load up my url:
502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be
displayed. When the Web server (while acting as a gateway or proxy)
contacted the upstream content server, it received an invalid response
from the content server.
My setup in IIS is the following:
In ARR, I just ticked the Enable proxy option.
In URL Rewrite, I set up a rule with:
Match PRL Pattern = api/* (Using wildcards)
Action type = Rewrite
Rewrite URL: = api.example.com/{R:1}
I've made sure I can access the web services and data is returned correctly from the context of my web server. I've made sure the actual URL Rewrite rule is being triggered and forwarding the request correctly... but after that, I'm stuck. Any ideas?
