With these it helps I am using angularjs on the UI and it cant tell the difference between the server being down or a timeout both respond with something like the following. This is due to cors. When server is down or a request times out apache does not add the cors header. , Instead of Header set use Header always set:
Header always set Access-Control-Allow-Origin "*"

fixed the issue. Will look into that further Let's assume I have a FPGA/VHDL design that has two clock domains, and every path between one clock domain to anther clock domain has CDC synchronization code written in VHDL to make sure there are no meta-stability when passing information between crossing clock boundaries.
attribute ASYNC_REG : string;
attribute ASYNC_REG of a_r_clk_2 : signal is "TRUE"; -- Output of the first resync FF in clk_2
attribute ASYNC_REG of a_rr_clk_2 : signal is "TRUE"; -- Output of the second resync FF in clk_2
