我正在为我自己的项目使用标准的网络托管服务。
它使用了主域www和几个子域。我不需要在我的.htaccess文件中使用任何 Apache ReWrite 规则，我唯一要做的就是确保我的 CNAME 记录已更新。一切正常，我只是使用权限来限制对文件和文件夹的访问..
我最近在主www级别安装了 Elgg，现在我所有保持不变的子域都会403出错。该消息指向我的 htaccess 文件是罪魁祸首。
我想知道如何配置 htaccess 文件以允许子域gadgets.mydomain.com再次工作但不允许访问同一域下的其他文件夹？没有更改任何权限，它们保持为 755。
这是标准的 Elgg htaccess 文件。我将如何编辑它？
# Elgg htaccess directives
<Files "htaccess_dist">
order allow,deny
deny from all
</Files>
# Don't allow listing directories
Options -Indexes
# Follow symbolic links
Options +FollowSymLinks

# REWRITE RULES
<IfModule mod_rewrite.c>
RewriteEngine on
# If Elgg is in a subdirectory on your site, you might need to add a RewriteBase line
# containing the path from your site root to elgg's root. e.g. If your site is
# http://example.com/ and Elgg is in http://example.com/sites/elgg/, you might need
#
#RewriteBase /sites/elgg/
#
# here, only without the # in front.
#
# If you're not running Elgg in a subdirectory on your site, but still getting lots
# of 404 errors beyond the front page, you could instead try:
#
#RewriteBase /
# If your users receive the message "Sorry, logging in from a different domain is not permitted"
# you must make sure your login form is served from the same hostname as your site pages.
# See http://docs.elgg.org/wiki/Login_token_mismatch_error for more info.
#
# If you must add RewriteRules to change hostname, add them directly below (above all the others)
# In for backwards compatibility
