Won't purge single posts & wrong urls

[someguy9]

I noticed in the varnishlog my blog (located at /blog) would appear as /blog/blog in the urls

I added this to the WPVarnishPurgeObject function to fix the issue above
add after "$wpv_url = $wpv_blogaddr . $wpv_url;"

if (0 === strpos($wpv_url, $wpv_blogaddr . $wpv_blogaddr)) {
    $wpv_url = str_replace($wpv_blogaddr . $wpv_blogaddr, $wpv_blogaddr, $wpv_url);
}

Also single posts wouldn't purge so I added

$this->WPVarnishPurgeObject($wpv_url);

before "// Add support for multipage content for posts and pages"

hope this helps someone (I'm running WP 4.1)
