I'm trying to configure PHP and IIS to allow uploading large files < 500MB.
When I upload a small test file everything works fine (74.1KB).
However when I upload a larger test file (50MB) the browser sits for 5 seconds then gives a 404 error.
When I upload an even larger file (309MB) the brwoser sits for 28 seconds then gives a 404 error.
According to phpinfo()
Directive Local Value Master Value
file_uploads On On
upload_max_filesize 2G 2G
max_input_time 900 900
memory_limit 2G 2G
max_execution_time 900 900
post_max_size 2G 2G
I feel like I'm missing some basic configuration but I'm not having any success figuring out what it is or what logs to check to see where the problem is.
Any ideas where I should be looking?
