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!

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
