php curl http redirect cookies

I'm working on a project and hit a roadblock. Hey everyone, I'm running into an issue that's driving me crazy. I'm encountering an issue where my cURL request in PHP 8.1 is not properly handling 302 redirects as expected. I want to follow redirects automatically but it seems like the `CURLOPT_FOLLOWLOCATION` option isn't working correctly for my use case. When I make a request to a URL that returns a 302 status, the cURL request successfully reaches the redirected URL, but the response seems to lose some headers, specifically the `Set-Cookie` headers from the initial response. I've set up the cURL options as follows: ```php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://example.com/redirect'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt'); $response = curl_exec($ch); $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); ``` After executing the cURL request, I check the `$response` for headers returned, but the `Set-Cookie` header from the original response is missing. I expected it to be preserved in the cookies stored in `cookie.txt`, but it seems like only cookies from the final URL are being saved. I have tested this with both `CURLOPT_RETURNTRANSFER` set to true and false, but the behavior remains the same. Is there a configuration or setting I might be missing to ensure that cookies from the original response are retained during the redirect process? I've confirmed that the initial response does indeed send `Set-Cookie`, and it seems that the behavior differs when tested with `curl` in the command line. Any help would be greatly appreciated. This is part of a larger web app I'm building. I'm working on a web app that needs to handle this. Any ideas what could be causing this? I'd really appreciate any guidance on this.
