I'm using shared hosting with minimal access to any configuration settings.I've created a more or less empty HTML file, emptypage.html, with the following contents:<!DOCTYPE html><html><body></body></html>When I pass an encoded URL as a query string parameter, I get a 403 error from the server.Example URL:http://example.com/emptypage.html?u=http%3A%2F%2Fexample%2EorgHowever, if the encoded URL is for the same domain, the page displays normally.Example URL:http://example.com/emptypage.html?u=http%3A%2F%2Fexample%2EcomSimilarly, if the 'h' from the beginning of the URL is removed, the page displays normally.Example URL:http://example.com/emptypage.html?u=ttp%3A%2F%2Fexample%2EorgCould this be the result of some web server setting that I may be able to override in my local .htaccess file?  My web host uses Apache (not sure which version).NOTE: I asked a similar question earlier but it was not well understood and was put on hold.  I've since done more research to figure out what exact conditions are yielding this issue.
403 when query string parameter contains an encoded URL
htaccess;apache;403 forbidden
