Varnish cache - How to purge/delete cache only for Home page

I'm using Drupal 7 latest dev version.

I have installed Varnish and Expire modules and setup them. They are working very well but I have one problem regarding deleting cache from varnish.

The problem is how to **delete** varnish cache only for **index(home)** page and not to delete cache for other pages. I look at he varnish log and I found that whole varnish cache is deleted every time Drupal executes command

ban req.http.host ~

[To see links please register here]

&& req.url ~ "/"

This command is executed by varnish module or expire module and it means delete cache of home(index) page. But as I see it is deleting all cached pages in varnish.


**How to fix this? How can I delete only cache for home page?**

You should invoke other command from Drupal:

ban req.http.host ~

[To see links please register here]

&& req.url ~ "^/$"
Cache invalidated for whole site, because regexp "/" matches all URLs

You could also do

ban req.http.host ==

[To see links please register here]

&& ban req.url == "/"

Will this Drupal Purge module do it for you?

[To see links please register here]

There is the [Varnish HTTP Accelerator Integration][1] module, which provides a very useful function varnish_purge().

Use the function to clear the varnish cache.
