Question

I want to rewrite test.com to test.com/context.

The browser returns redirection recursion error.

Anyone has a clue?

I put below in httpd-vhosts.conf.

<VirtualHost *:80>
    ServerName test.com

    JkMount /* mschoi
    ErrorLog logs/mschoi-error_log
    CustomLog logs/mschoi-acces_log common

    RewriteEngine On
    RewriteRule ^/(.*)$ /context/$1 [L,R]

</VirtualHost>

httpd.conf
Include conf/extra/httpd-vhosts.conf

This is a simple case of your rule matching /context again when it rewrites. You can just use a RewriteCond to avoid it:

RewriteEngine On
# Rewrite only if the request doesn't already match /context
RewriteCond %{REQUEST_URI} !^/context
RewriteRule ^/(.*)$ /context/$1 [L,R]

If the files being accessed actually exist (rather than a rewrite pattern) you can test for and not rewrite any real existing files:

RewriteEngine On
# If the requested resource is not actually a real file or directory (doesn't exist)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/(.*)$ /context/$1 [L,R]

Edit after comment to explain:

Not only per-directory rules can cause recursion. In this case, it is the simple matter that /(.*) matches anything and that gets appended unconditionally to /content. Since the [R] flag is present to redirect and each of these is a new request, it becomes a redirection chain of :

/something
/content/something
/content/content/something
/content/content/content/something

Subsequent redirects always continue to match the leading /content as well as what follows with /(.*) and append to it.
