Hey all,

I’m using Zlib::Deflate.deflate to deflate a response from an HTTP  
request to return back to the browser. The requests accept gzip,deflate  
but when I return the deflated data the browser is not handling it  
correctly…

any ideas where to look to debug?

thanks  
Aaron

little more info… I’m using WebRick, LightTPD, and Mongrel…

I was looking at mongrel source and see that I was missing the  
Content-Encoding. But not sure where to set that for each server…
