Hi all! I'm currently using FastCGI for an application - in particular, Ceph's radosgw (S3 endpoint). I was told to use mod_fastcgi as mod_fcgid doesn't handle large request bodies appropriately. Yet, when I looked at the mod_fastcgi code, I shrieked in horror. =)
In looking at add_request_body in fcgid_bridge.c, it looks like we read the request body into memory and if it crosses a threshold, we spool it to disk. After everything is read from the client, then mod_fcgid begins to write to the FastCGI socket. In my use case, we would be PUT'ing large request bodies that are many GB in size - so, I'd rather just stream it to the FastCGI socket and take the hit on potentially blocking other incoming requests. (In our case, it makes no sense to spool the request body to local disk.) Anyway, I'm diving into the code a bit - but, I figured it might be useful to see if anyone else has any thoughts about how to handle large request bodies with mod_fcgid. Happy holidays! -- justin
