Re: What do you think about Lighttpd?
Ah, OK so I shouldn't panic until a browser ships with pipelining enabled by default. HTTP pipelining would be nice, as in limited tests, it had a nice performance increase on sites with lots of little images/css/etc. On 3/1/07, Greg Ames [EMAIL PROTECTED] wrote: --- steve [EMAIL PROTECTED] wrote: I use it too, and have meddled with it enough at a source level to feel comfortable running it.

Re: util_ldap.c use of hardcoded sizelimit on ldap_search_ext_s causing error
