In addition to being a 'basic' web server, and providing static and dynamic content to end-users, Apache httpd (as well as most other web servers) can also act as a reverse proxy server, also-known-as a 'gateway' server.
In such scenarios, httpd itself does not generate or host the data, but rather the content is obtained by one or several backend servers, which normally have no direct connection to the external network. As httpd receives a request from a client, the request itself is proxied to one of these backend servers, which then handles the request, generates the content and then sends this content back to httpd, which then generates the actual HTTP response back to the client.

There are numerous reasons for such an implementation, but generally the typical rationales are due to security, high-availability, load-balancing and centralized authentication/authorization. It is critical in these implementations that the layout, design and architecture of the backend infrastructure (those servers which actually handle the requests) are insulated and protected from the outside; as far as the client is concerned, the reverse proxy server is the sole source of all content.
Since Open TSDB wont support https to send data(via REST API), we want to create a https proxy in apache or 'Apache Tomcat'. For example, the local machine has both TSDB and Apahce. For example, the local machine has both TSDB and Apahce. Under Apache 1.x, modproxy only supported HTTP/1.0, but from Apache 2.0, it supports HTTP/1.1. This distinction is particularly important in a proxy, because one of the most significant changes between the two protocol versions is that HTTP/1.1 introduces rich new cache control mechanisms. You'll need modssl, modproxy and optionally modrewrite. Depending on your distribution and Apache version you may have to check if modproxyconnect and modproxyhttp are loaded as well. The directives for enabling SSL proxy support are in modssl. Apache HTTP Proxy is a proxy service that can be used to distribute updates to client computers. Apache HTTP Proxy performs a similar role to the mirror server feature popular in ERA 5 and earlier. To install Apache HTTP Proxy, read the instructions for Windows, Linux, or Virtual Appliance.
