Hi

I posted the recent thread on problems with body\_filter\_by\_lua, and I  
think it finally has to do with the fact that my browser allows gzipped  
data, and the server in my example returns gzipped data. I only found  
out using wireshark.

Could it be that the gzipped data don’t even reach the lua code?

Thanks

Bart
