We're using NGINX as our main web server, after moving away from Apache. We recently decided to test ClamAV integration, to make sure files uploaded by users are thoroughly scanned prior to transfer to Amazon S3.
I'm looking for an easy way to integrate NGINX and ClamAV, i.e. every file uploaded to a temporary folder gets scanned, and removed if found to be infected.
mod_clamav for Apache, but no similar support for NGINX. Is there a good way to integrate ClamAV and NGINX, or should it be done on an application level (i.e., download the file, and then trigger an application that will scan prior to uploading)?
