Redirects are a fundamental concept of the HTTP protocols, allowing requests to get turned to other resources containing the desired data.
By default, cURL commands don't follow redirects. For example, let's attempt to request httpbin.dev/absolute-redirect/:n. It redirects the request for x number of times:
curl https://httpbin.dev/absolute-redirect/6
Executing the above command will return nothing, as the request didn't proceed to its final destination. To make cURL follow redirects, we can use the -L or --location:
curl -L https://httpbin.dev/absolute-redirect/6
The above cURL request will follow the redirects 6 times and finally return a response:
{
"args": {},
"headers": {
"Accept": [
"*/*"
],
"Accept-Encoding": [
"gzip"
],
"Host": [
"httpbin.dev"
],
"User-Agent": [
"curl/8.4.0"
]
},
"url": "https://httpbin.dev/get"
}
By default, the -L or --location cURL options enable redirects following for a maximum of 50 times. To override the redirects limit, we can use the --max-redirs cURL option:
curl -L https://httpbin.dev/absolute-redirect/51 --max-redirs 51
