How to use varnish cache with set-cookie named mp3list and phpsessionid

cookievarnish

I am new to php and i am interested to use varnish to improve site performance.

I installed the latest version of varnish: 4.0.2 varnish

I use a cookie named (mp3list and phpsessionid) so I can't cache my pages. I used vcl with:

$sub vcl_recv {
  call normalize_req_url;
set req.http.Cookie = regsub(req.http.Cookie, "^;\s*", "");
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
# If the requested URL starts like "/cart.asp" then immediately pass it to the given
# backend and DO NOT cache the result ("pass" basically means "bypass the cache").
if (req.url ~ "^/playlist\.php$") {
   return (pass);
   }
}
sub vcl_backend_response {
 # Happens after we have read the response headers from the backend.
 #
 # Here you clean the response headers, removing silly Set-Cookie headers
 # and other mistakes your backend does.
 if (beresp.http.Set-Cookie)
 {
  set beresp.http.Set-Cookie = regsub(beresp.http.Set-Cookie, "^php","");
  if (beresp.http.Set-Cookie == "")
    {
        unset beresp.http.Set-Cookie;
    }
  }
 unset beresp.http.Cache-Control;
 set beresp.http.Cache-Control = "public";
 }
 sub vcl_deliver {
 # Happens when we have all the pieces we need, and are about to send the
 # response to the client.
 #
 # You can do accounting or modifying the final object here.
 # Was a HIT or a MISS?

 if ( obj.hits > 0 )
 {
  set resp.http.X-Cache = "HIT";
 }
 else
 {
  set resp.http.X-Cache = "MISS";
 } 
 # And add the number of hits in the header:
  set resp.http.X-Cache-Hits = obj.hits;
 }
 sub normalize_req_url {
 # Strip out Google Analytics campaign variables. They are only needed
 # by the javascript running on the page
 # utm_source, utm_medium, utm_campaign, gclid, ...
 if(req.url ~ "(\?|&)(gclid|cx|ie|cof|siteurl|zanpid|origin|utm_[a-z]+|mr:[A-z]+)=") {
    set req.url = regsuball(req.url, "(gclid|cx|ie|cof|siteurl|zanpid|origin|utm_[a-z]+|mr:[A-               z]+)=[%.-_A-z0-9]+&?", "");
  }
  set req.url = regsub(req.url, "(\?&?)$", "");
  }
  sub vcl_hash {
  hash_data(req.url);
  if (req.http.host) {
  hash_data(req.http.host);
  } else {
  hash_data(server.ip);
  }
  hash_data(req.http.Cookie);
  }

Now I removed mp3list using this, still phpsessid is there, what can I do to remove phpsessid?

Does someone know how to bypass phpsessid and edit VCL, to use varnish effectively?

I'm not entirely sure what you're after, you want to remove the PHPSESSID cookie? There's a guide here; https://www.varnish-cache.org/trac/wiki/VCLExampleRemovingSomeCookies
