Do I Need a Reverse Proxy?

Is Nginx a load balancer or reverse proxy?

I have a web application I am trying to deploy, this application is based on the Laravel Framework using Apache 2.4 as the webserver and Nginx as the engine.

I had wanted to do some validation on the request before passing it along to the web server, but I'm not sure if I need to do that via nginx or the web server. The process would be: nginx - validate - apache. OR
Nginx can receive the request - validates - passes along to apache. My main concern is load balancing, if I put the nginx in front of each apache instance then it seems to be the reverse proxy, but I am unsure if this is what I need. Does anyone have any feedback on this? EDIT: So far, Apache is set up to just pass every request along to the index.php file.

Nginx should do the validation. If you are doing basic level validation over the request (after parsing it to make sure it is a GET request) then it should be handled comfortably by the server and not nginx.

When possible, make sure to configure the level of validation you need to do and do it at the top of your request processing code.

What is difference between proxy and reverse proxy?

Wikipedia defines a reverse proxy in a very broad fashion: A reverse or upstream proxy acts as a single host that directs multiple Domain Name System (DNS) name resolution requests for the same HTTP host name to one of multiple pairings of DNS server and web server. It does not overlap with a web server's usual function of serving pages or load balancing (but see Cache proxy). Limiting the term to web servers solves the problem of the wording you tried to use in your question; we can see by this wikipedia article how HTTPReverseController isn't a reverse proxy but a Web API controller. A proxy can be either transparent, that is where it sends the user directly to the destination server, or a transparent proxy like Squid is a software that hosts caching and other optimization services. In addition a proxy might act as the middleman between a client and a server to security-encode or otherwise filter communications. This last service is used mostly on the backend of enterprise networks whose firewalls only allow certain URLs (the backend firewall) and nothing else (policy from the network admins using private nets).

Why Use a Reverse Proxy?

What is a reverse proxy Nginx?

"Nginx is a free-software, open-source HTTP and HTTPS web server for Linux, UNIX and Windows. It was developed by Dongsheng "Steve "Woo" Ma and Igor Sysoev for advanced high-performance HTTP caching in web browsers and HTTP proxies."

Configuration. One single configuration file per server using the "server" directive, although load balancing can be performed if desired using httpport variables with weight, roundrobin, random or hash filter. Directives. Requests setup in front of the application at agent level; if not told to "pass through", then proxied. Variables are logged to access.log by default, can be modified with proxybuffering and proxyreadbuffering.

Filters can increment a counter into a byte range ( byte - byte, byte - byte, etc. In practice. Obviously Not Yet Ready Warning The fastest way to load-test and/or test baseline performance is still with the ApacheBench (AB) benchmarking tool (see Hannu Kannila's excellent presentation "From BadBoyToNgninx" at the BlueHatTalk), and it will very likely return giant results compared to what you get with Nginx. When nullifying the difference between the two, you are passing UnitTests : this just means that conventional systems tend to cost users 12% because system-under-test ( x ) goes through ( y ) plus ( z ).

Do I Need a Reverse Proxy?

Avers hasn't been noted as a requirement, but it certainly could be used if you have complex routing rules. A reverse proxy is often the real power in which regular routes are blocked by more complex ones, so it could be worth considering if you have enough routes to provide your clients with a useful experience. Generally though, Avers should be easy to build and give you just as much flexibility as using a reverse proxy.

How Do I Get Started? Building a web app using Avers can be as simple as running the one command. However to make more elaborate applications and speed things up, there are a variety of options available.

Preset Routes. As mentioned above, Avers provides an easy way to trim down the potential permutations of requests. Requests to certain URLs will be blocked off while requests to other URLs, be they your own or hosted elsewhere, will be accepted. You can use presets in a number of ways, such as being included in a route or override a route.

When you are providing your own custom URLs Avers also gives you the ability to let them play back normally by using definitions. This a good way to go if you need access to your URL space, or simply want more control over what your users see.

Custom Routes. You can implement your own servers on your own domain, if needed. You could have your own controller that computes responses to any request. You could even change the entire application using plugins - remember you can even prefix an image file for external redirect regardless of what `suffix` is set.

Preventing The Exceptions. Finally, whenever you configure routes, you create exceptions for yourself. If you accidentally add a route that allows requests for your own subdomain, you can prevent Avers from stopping it by configuring the result of a `prevent` method to avoid what it would otherwise do.

Lower case only. Perhaps the most important configuration tips we're giving out here (besides not allowing custom exceptions), is that Avers opts for matching your regular expressions with its lowercase only. You can bootstrap your server with this option by setting the `optPrefix: 'avers'` (and any options your modes) in `demo/server` (remember to `collapseMode: BOSS` as well while building).

How safe is Nginx reverse proxy?

it's a valid question since I really use something like this to give outside requests to my server running on Amazon EC2, and at the same time be Http:// www, Htttp:// allowing me to easily restrict access and shut down my server if there is any problem on the client's side.

I was just wondering What could/may happen when serving on the outside world with a reverse proxy? Could my server, for example, get hacked and used for attacking, including serve trojan files? My server can easily go down, and won't allow access (unless you have the private domain address returning some specific content to specified users and your server works as a single website, but in reality we have more than one site). Typically, for HTTP over SSL you use a reverse proxy such as nginx, it acts as a very good gate keeper, and hence relatively safe. The proxies usually utilize two nginx processes running under unique ports/websockets to complement eachother.
