regex - .htaccess redirect all pages to homepage except few of them -

i have site 2 sub pages want keep, want redirect other sub pages homepage. current htaccess code:

# disable varnish caching on server header set set-cookie "_asomcnc=1;   max-age=900; path=/;"  rewriteengine on  # redirect www rewritecond %{http_host} !^www\. rewriterule ^(.*)$ http://www.%{http_host}/$1 [r=301,l]  # redirect index.html root rewritebase / rewriterule ^index\.html$ / [nc,r,l]  # remove trailing slash rewriterule ^(.*)/$ /$1 [l,r=301] 

i tried few examples found here on stack overflow keep getting redirect loops, or css file , images not loaded. lets want load files these 2 folders:

• /css
• /images

and want keep 2 subpages:

• /subpage1.html
• /subpage2.html

everything else should redirected homepage.

to exclude pages being rewritten, can either use rewritecond %{request_uri} or short circuit rule chain.

to exit early, insert these rules @ beginning

rewriterule ^css - [l] rewriterule ^images - [l] rewriterule ^subpage1.html$ - [l] rewriterule ^subpage2.html$ - [l] 

and redirect else homepage, unless home page, of course

rewritecond %{request_uri} !^/$ rewriterule ^ / [r,l] 

---

to same rewritecond

rewritecond %{request_uri} !^/css rewritecond %{request_uri} !^/images rewritecond %{request_uri} !^/subpage1.html$ rewritecond %{request_uri} !^/subpage2.html$ rewritecond %{request_uri} !^/$ rewriterule ^ / [r,l] 

this redirects home page, if request_uri not css , not images , not subpage1.html , not subpage2.html , not home page.

when works should, may replace r r=301. never test r=301.
