.htaccess redirect all pages of old site to same pages on a subdirectory of a different site-CodePudding

I need to redirect all pages of an old site to a subdirectory of our main site. E.g.:

oldsite.com/page1 to mainsite.com/oldsite/page1

I have tried adding the following to the top of .htaccess

<IfModule mod_rewrite.c>

  RewriteEngine On

  RewriteCond %{HTTP_HOST} ^oldsite.com$ 

  RewriteCond (.*)$ http://www.mainsite.com/oldsite/$1 [R=301,L]

</IfModule>

When I open a fresh anonymous window, the redirect does not work, even on the homepage. So it is probably another rule getting in the way. The following is at the bottom of the .htaccess file:

# BEGIN W3TC Page Cache core
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{HTTPS} =on
    RewriteRule .* - [E=W3TC_SSL:_ssl]
    RewriteCond %{SERVER_PORT} =443
    RewriteRule .* - [E=W3TC_SSL:_ssl]
    RewriteCond %{HTTP:X-Forwarded-Proto} =https [NC]
    RewriteRule .* - [E=W3TC_SSL:_ssl]
    RewriteCond %{HTTP:Accept-Encoding} gzip
    RewriteRule .* - [E=W3TC_ENC:_gzip]
    RewriteCond %{HTTP_COOKIE} w3tc_preview [NC]
    RewriteRule .* - [E=W3TC_PREVIEW:_preview]
    RewriteCond %{REQUEST_METHOD} !=POST
    RewriteCond %{QUERY_STRING} =""
    RewriteCond %{HTTP_COOKIE} !(comment_author|wp\-postpass|w3tc_logged_out|wordpress_logged_in|wptouch_switch_toggle) [NC]
    RewriteCond %{REQUEST_URI} \/$
    RewriteCond "%{DOCUMENT_ROOT}/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html%{ENV:W3TC_ENC}" -f
    RewriteRule .* "/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_SSL}%{ENV:W3TC_PREVIEW}.html%{ENV:W3TC_ENC}" [L]
</IfModule>
# END W3TC Page Cache core
# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} (.*)\.(jpe?g|png)$
RewriteCond %{REQUEST_FILENAME}\.webp -f
RewriteCond %{QUERY_STRING} !type=original
RewriteRule (. )\.(jpe?g|png)$ %{REQUEST_FILENAME}.webp [T=image/webp,E=accept:1,L]
</IfModule>
<IfModule mod_headers.c>
Header append Vary Accept env=REDIRECT_accept
</IfModule>

Any ideas on what I should change to achieve my desired result?: oldsite.com/page1 to mainsite.com/oldsite/page1

Solved!

I removed all the rewrite rules that were already in there, apart from the wordpress one.

I then used this rule instead of the one I originally posted:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^oldsite.com$ [NC,OR]
  RewriteCond %{HTTP_HOST} ^www.oldsite.com$
  RewriteRule (.*)$ http://www.mainsite.com/oldsite/$1 [R=301,L]
</IfModule>
