Slice module

[Martijn Berkvens]

Hi,

First off, thank you for the work on the slice module. We’re currently using a lua implementation to achieve something similar but this has its shortcomings and we would prefer to use this module. 

We’ve been testing this module and when using range requests it works as expected, but when doing normal requests (without a request range) the module still slices the content when the configured slice size is met resulting in corrupt data as it will only serve out the configured slice size and not the entire requested file.
We run into these issues because a server or location configuration within nginx would service both normal requests as range requests and we have files exceeding the slice size in both cases. 

Ideally the slice module would only do its magic when a request contains $http_range. We’ve tried creating a map which would set the slice size to 0 (to disable slicing) when no $http_range is present, but unfortunately the slice directive currently does not support variables. 

For our use case it would most likely be sufficient to add variable support to the slice directive. It is understood and acceptable that we would have duplicate cached content in cases where we have both the sliced versions of the file as the entire file. 


Thanks again!

Martijn
