Exclude page from WordPress Processing-CodePudding

I have a main site with multiple pages managed by WordPress. I also have a custom developed page on a different path, which is required by Google Auth as a callback. This page contains custom JS and works fine most cases. The callback by Google adds a whole plethora of parameters outside of our control, such as this example:

https://<mydomain>
          / Home page managed by WP
          /-- Sub pages managed by WP
          /scheduler/googleCalendarRegistration.html <== custom page NOT managed by WP

In some cases WordPress interfers and throws a "404 - Not found error", when the custom page is called.

I need help either editing .htaccess or installing a plugin, so that my custom page is not funneled through the WP engine.

CodePudding user response：

You can do something like the following at the very top of the root .htaccess file to prevent any further processing (including routing the URL through WordPress) when the stated URL-path is requested:

RewriteRule ^/?scheduler/googleCalendarRegistration\.html$ - [END]

This does not check the query string (so any query string is permitted).
