How I can write a condition in the nginx config testing if a q parameter was entered in the URL?
This doesn't work:
if ($arg_q) {
return 301 "/someurl";
}
It catches URLs like
/search?entered_search=1&q=123
But it doesn't catch URLs like
/search?entered_search=1&q=
Something like this might work. It says "if the query string contains the sequence 'q=' send a redirect". At least that's what I think it says, I'm not great with regex. I've tested it and it works, but there may be side effects depending what query strings you could get.
if ($query_string ~ q=) {
return 301 "https://www.example.com";
}
This answer helped me work it out.
