Indeed mod_perl generates chunked response. Finally we have the same result. I don't see any problem at this moment. You would probably wish to append your script with additional output after the empty string? Something like: #!/usr/bin/perl $|=1; print "Content-Type: text/html\n\n"; print "hello world<P>"; # This line causes the error (?) print ""; print "hello again<P>"; --- It may cause a problem for chunked output if mod_deflate does not care to keep internal buffer and check its size when flushing...
