annotate src/mail/ngx_mail_proxy_module.c @ 8099:17d6a537fb1b
Increased maximum read PROXY protocol header size.
Maximum size for reading the PROXY protocol header is increased to 4096 to
accommodate a bigger number of TLVs, which are supported since cca4c8a715de.
Maximum size for writing the PROXY protocol header is not changed since only
version 1 is currently supported.
