Description:

Hi, I saw this problem on 4.3.3, but I haven't see it in change-log of 4.3.4, so, I'm reporting it.

I have several virtualhosts. One of my virtual host have  include_path changed in .httacces.

Sometimes (not often) another virtualhost uses this include_path. The frequency is about once per 100 requests...

I have just installed 4.3.4, so, I'll be watching my logs...

I'm using these modules of Apache:
Compiled in modules:
  core.c
  mod_access.c
  mod_auth.c
  mod_include.c
  mod_log_config.c
  mod_env.c
  mod_setenvif.c
  mod_ssl.c
  prefork.c
  http_core.c
  mod_mime.c
  mod_status.c
  mod_autoindex.c
  mod_asis.c
  mod_suexec.c
  mod_cgi.c
  mod_negotiation.c
  mod_dir.c
  mod_imap.c
  mod_actions.c
  mod_alias.c
  mod_so.c

If you think, I can help, contact me, please.

Regards
