A Movable Type on JustHost.com; configuration tips

More than one year experience using a Movable Type (MT) pushed me diving into a hosting jungle to economize allowance. This year's hive is justhost.com. I encountered several anomalies in the middle of MT migration, then, fixed them by analyzing error logs as well as referring to MT documentation. Here are several configuration tips undocumented elsewhere. Ah, let me know if somebody had already documented :-) I hope followings will help you enjoying MT.

In .htaccess, add two lines below

# 1. to protect directory info. (blog archive) from browsing
Options -Indexes

# 2. my glue; optional (not strictly applicable to MT)
# to run php codes in html
AddType application/x-httpd-php5 .html

In mt-config.cgi, add two lines below

HTMLUmask 0022
DirUmask 0022

If you don't add HTMLUmask/DirUmask, MT will generate world writable (-rw-rw-rw-)HTMLs and directories not welcomed by justhost.com http servers. As a result, nothing will be shown on web browser.
