Nginx Robots.Txt Exclude From Caching
Caching is an important part of any website as it allows content to be delivered quickly and efficiently to its users. But, as with any technology, there are times when it can be misused. This is where the nginx robots.txt file comes in. Using this file, you can configure your nginx server to tell search engines and web crawlers which pages to not cache. With this article, you’ll learn how to exclude pages from caching using the nginx robots.txt file.
What Is Caching?
Caching is a process by which a website stores its content in a temporary storage location called a “cache”. Caching allows more efficient delivery of content by reducing the amount of data that needs to be transmitted from the server to the user. When a user requests a page that is cached, the page is loaded from the cache instead of from its original location. This can significantly speed up the website.
What Is the robots.txt File for?
The robots.txt file is a text file located in the root directory of a website. It is used to communicate to robots (a.k.a. web crawlers) which pages of the website should not be visited by them. It can also be used to prevent search engine indexing of certain pages. The nginx robots.txt file is used to configure the nginx server to tell search engines and web crawlers which pages should not be crawled and/or cached.
Using robots.txt to Exclude Pages from Caching
To exclude individual pages or folders from caching using the nginx robots.txt file, you must first create the file. To do this, you must first create a text file named “robots.txt” in the root directory of your website. Inside this file, add the following line of code:
Disallow: /path/to/directory/or/file
This tells search engine robots and web crawlers not to crawl and/or cache the specific directory or file specified. You can add multiple lines of this code for different pages or directories you’d like to exclude from caching. There are other directives you can include in the robots.txt file, such as Sitemap directives and Link directives, for more advanced control over the caching of your webpages.
Example nginx robots.txt File
Here is an example of an nginx robots.txt file that excludes multiple pages and directories from being crawled or cached:
User-agent: Googlebot
Allow:
Disallow: /private-page/
Disallow: /secret-directory/
User-agent: *
Disallow: /customer-account/
This tells both Googlebot and other robots not to crawl the pages and directories specified.
Why Exclude Pages From Caching?
There are many reasons why you might wish to exclude certain pages from being cached. For example, if you have pages with sensitive information or require a user login, you may not want these pages to be cached. In addition, excluding some pages, such as pages with complex JavaScript code, can improve the performance of the site if they are not cached.
Conclusion
The nginx robots.txt file can be used to configure your nginx server to tell search engines and web crawlers which pages should not be crawled or cached. This can be used to prevent sensitive information from being cached, as well as to improve site performance. It’s important to remember that the robots.txt file only tells robots which pages should not be crawled or cached. It does not effectively hide content on your website, so it should not be relied upon for security.
