Previous Comments: ------------------------------------------------------------------------ [2020-07-14 07:26:05] sjon@php.net can you clarify what you think the bug is? The ignored Content-Length on the 302 response is perfectly valid, and I've tested with CURLOPT_HEADER=true and it correctly includes the Content-Length header in both the 302 and the final response ------------------------------------------------------------------------ [2020-07-14 07:00:02] kaa at g-it dot su Description: ------------ Right version of php I'm using is 7.2.24. Installed from Ubuntu repos. PHP_curl with enabled CURLOPT_FOLLOWLOCATION lost http header "Content-Length" on second redirect with 302 "Redirect temporary".
