Bash – How to use zipsplit (or equivalent) on very large files

DotNetZip will allow you to do this from PowerShell. It is not a one-liner, but the library will allow you to write the PowerShell script you need.

You can also use the COM interface, see Compress Files with Windows PowerShell then package a Windows Vista Sidebar Gadget.

Googling "zip powershell" or "unzip powershell" might also turn up useful results.

Use curl or another tool to check the headers to be sure you are specifying the correct mime type for the PDF file. You should be pulling in mime.types into your config.

If you are doing that, then I would drop the client_* and related buffers. I have nginx working without these and serving PDF/SWF without issue.
