Max File Size Allowed In Cache

[martinproinity]

Thanks Maxim. Is it possible the filter on a value "larger than" or "smaller
than"? How would the regex in the map block look like? e.g. smaller than
1000000?

I tried something like this, which is not working:
map $upstream_http_content_length $docache {
        default         0;
        "~*([1-9][0-9]{0,6}|1000)$" 1;
}
