Subject Re: Concurrent access to request body by multiple modules
Date Tue, 01 Dec 2020 15:44:12 GMT
Hi Nick,

thank you for the quick answer and the pointer to mod_request. I've had 
a look at it before but, as you already pointed out, it is not fit for 
the case at hand: the server I am deploying this module with will see 
arbitrary-sized requests with files up to several GB in size. Keeping 
request-bodies of that size in RAM when several concurrent requests fly 
in will not be possible.

So, I will have a closer look at writing an input filter for this 
purpose, which is what I had in mind as a viable option already. But I 
wanted to check if anyone here had a different solution idea I wasn't 

Thanks again and have a nice day.
