Nginx Proxy_Pass Post Request
What Is an Nginx Proxy_Pass Post Request?
A Nginx Proxy_Pass Post request is a particular type of web request that allows a web server to forward a request to another destination. It is often used with CMS (Content Management System) applications or web applications where I/O resources or web-based user interfaces need to be made available to users. The Nginx Proxy_Pass Post request is one of the most commonly used web requests the Nginx web server. It can be used to send POST request to a different origin server, allow requests for URLs that do not exist on the current server and direct a request to a static content server. Nginx does not automatically create a response for POST requests, but instead returns a 307 Temporary Redirect status to ensure that web browsers will continue to resend the statement.
How Nginx Proxy_Pass Post Requests Work
The Nginx web server will process a Proxy_Pass Post request as it processes any other web request. It will read the headers, request body and cookies. Any Post Parameters that the origin server required to process the request will be recalled and processed. If the parameters received match what the origin server expects, then the Nginx web server will send the Post request to the designated origin server. If the parameters do not match, then the Nginx web server will return an error code.
Once the Nginx web server has sent the request to the origin server, the origin server will perform the requested action. If one is required, the origin server will send back a response to the Nginx web server. The Nginx web server in turn will send the response to the requesting Web browser.
Uses of Nginx Proxy_Pass Post Requests
Nginx Proxy_Pass Post requests are used when a user on your site wants to make a request that involves processing on the origin server. This can range from a new blog entry to a full user registration. In these circumstances Nginx will use the Proxy_Pass Post request to direct the user’s request to the origin server. For example, if the user wanted to post a blog entry, the Nginx web server would forward the required parameters to the origin server as per the example below:
POST /path/to/blog/ HTTP/1.1
Host: www.origin_server.com
Content-Type: application/x-www-form-urlencoded
Content-Length: length
title=This+is+my+blog+title&body=This+is+the+body+text+for+the+blog+post
The Nginx web server could also use the Proxy_Pass Post request to allow requests for URLs that do not exist on the current server. For example, a request for ‘/latest’ could be passed onto an origin server that is running an application that can return the latest news items.
Advantages of Using Nginx Proxy_Pass Post Requests
The main advantage of using Nginx Proxy_Pass Post requests is the increased efficiency that this type of request allows. Because the request is sent directly to the origin server, response time is significantly reduced, as the request does not need to go through the same filtering process as other requests typically would.
This type of request can also be used to leverage the capabilities of other servers and applications. For example, if a request is made for a newsletter sign-up form, then that request can be sent to an origin server that hosts a subscription service. This reduces the workload on the current server and allows users to sign-up to the newsletter without interruption.
Other Considerations for Nginx Requests
When using Nginx Proxy_Pass Post requests, it is important to consider the security implications of such a request. If the origin server is not secure enough, then any data sent in this type of request could be compromised. It is therefore important to thoroughly check the security of the origin server before sending any confidential data.
It is also important to ensure that the origin server is correctly configured before allowing any requests to be sent to it. The origin server should be set up to correctly process the parameters sent to it with the request, otherwise it could lead to unexpected results or potential errors.
