Not sure if url rewrite helper is slowing down process because via
cache manager interface it didn't show any connection back log. What
information I should look for in cache manager to find out the cause
of the slow serving of requests ?

Henrik / Amos,
Tried using these setting and I could see see delay in serving the
requests even for cached objects.

Henrik,
With this approach I see that only one redirector process is being
used and requests are processed in serial order. This causes delay in
serving the objects and even response for cache object is slower.
I tried changing url_rewrite_concurrency to 1 but with this setting
squid is not
There was mistake on my part I should have used following script to
process concurrent requests. Its working properly now.
#!/usr/bin/perl -an
BEGIN { $|=1; }
$id = $F[0];
$url = $F[1];
$url =~ s/\?.*//;
print $id $url\n;
next;

We use query string in each url for bursting cache at client end (
browser) hence its not important for us and it won't provide any
incorrect results. We already use similar configuration at CDN level.
We are trying to add squid layer between origin and CDN to reduce the
load on our origin

For certain request we don't want client browser to look for object in
its cache and everything should be served fresh. CDN will determine
expire time for the object. Some of these objects doesn't send out

No, since the backend server is not interested in this dummy query
string an url rewriter is better.

It's capable to handle the concurrent helper mode yes. It doesn't
process requests in parallell, but you don't need to.
