I just wanted to know if there are any updates regarding the corrupted  
response headers:

I am trying to use fastcgi\_cache\_bypass to request a fresh response from  
the PHP-FPM backend and store it in cache when $http\_nocache is set.

I can’t use fastcgi\_no\_cache because I want the response to be cached  
for all future requests when $http\_nocache isn’t set.

Any updates on whether fastcgi\_cache\_bypass is supposed to work are  
really appreciated!  
Thanks!

As there has been no new releases in the intervening period, I think the  
answer is obvious.

As a work around, it may be possible to use 3rd modules like echo and  
proxy\_purge to clear the cache before fulfilling the request whenever  
$nocache is set so that a fresh copy is cached afterwards.

Never tried it before but looking at the docs, I’ll think it should be  
within their range of capabilities.
