Hello,  
is there a technical reason why the WebDAV module (for PUTs) always  
makes a temp file rather than use/honour memory buffer  
(client\_body\_buffer\_size)?

It will use memory buffer for intermediate data, but as it needs  
file on disk anyway - data are always written to a file.

Yes, and that’s why docs explicitly recommend using  
client\_proxy\_temp on the same file system:
