Subject: @- Improved ISAPI module - it should no longer be necessary to set PHP as
X-Git-Tag: BEFORE_SAPI_POST_PATCH_17_FEB_2000~26
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e9dcdb8f97fd167049f8634897876b145660a0aa;p=php

@- Improved ISAPI module - it should no longer be necessary to set PHP as
@  an ISAPI filter, only as an ISAPI extension, unless you wish to perform
@  authentication using PHP.  This didn't yet get enough testing, but it
@  should work (Zeev)
- Fixed auth_user/auth_password memory leak (I didn't have time to test it under
  Apache, feedback welcome!)
