Part of my default .htaccess contain the following lines
IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*
<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
What do they do? What having deny first and then allow mean? Will they prevent search engines from crawling my site? If so, will removing them have any effects on site security? Or how could they be modified? Thanks.
