Using mod_rewrite to block access based on REQUEST_METHOD + HTTP header

I want to use mod_rewrite to return 403 Forbidden when the REQUEST_METHOD is GET and when a specific custom header is missing. But I want to allow through requests with the OPTIONS verb even if that custom header is missing.



This is what I am using currently:



RewriteEngine On
RewriteCond %REQUEST_METHOD =GET 
RewriteCond %HTTP:SomeHeader ^$
RewriteRule .* - [F]


The GET behavior seems to be working fine (if header supplied I get back 200, without it I get 403). But I am also seeing that same behavior for OPTIONS (403 unless I provide header, then 200).



It seems like when the HTTP verb is OPTIONS the first RewriteCond should be failing, but somehow it seems like it is "passing" and continuing on with the other condition + rule.



Any thoughts on what is going on here? Thanks in advance!

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
