.htaccess question - Timeout and LimitRequestBody directives

I notice that in my webserver’s httpd.conf file, Timeout is set to 300 (seconds). Now I cannot edit httpd.conf since I’m on a shared server, so what directive can I add to .htaccess that changes the default 300 seconds to something like 60 seconds?

Also what about the directive LimitRequestBody? Can I similarly add it to .htaccess? If so how?

ok I just found out TimeOut cannot be used in .htaccess:

http://httpd.apache.org/docs/mod/core.html#timeout

But LimitRequestBody can:

http://httpd.apache.org/docs/mod/core.html#limitrequestbody

I just added a line in .htaccess:

LimitRequestBody 102400

to limit HTTP transfer message body to 100Kb. So far it seems to work okay.
