Subject Re: [users@httpd] Re: HTTP doesn't work after upgrading from 2.0.55 to 2.2.15
Date Fri, 28 May 2010 08:08:42 GMT
Hi William,

I gave you the incorrect information in the previous post.

cgi_read_stdout() in cgi_bucket_read() in mod_cgi.c, the data length is 806
followed by 0. (Not the 0 and 5 buckets)
then ap_core_output_filter() found a 0 length bucket, and appended a
last-chunk bucket?

Thanks

Best regards,
honercek
