# Purge Cache

Once a file is delivered through CDN Link, that means the file is distributed to 200+ Cloud Cache servers around the world and also stored in our internal caches.

Let's say you have a published image called `john.imagemash.io/w_100/logos/logo.png`, even if you delete the object from your storage or rename it, the file will be accessible from `john.imagemash.io/w_100/logos/logo.png`. Because it is still a valid file in Caches.\
\
Then you have a couple of options to overcome this situation.

* Add a dummy query to your file. (Random string. Split with `?` )\
  Eg. john.imagemash.io/w\_100/logos/logo.png<mark style="color:green;">?1234</mark>
* Change the name of your file and use the new one. Eg. `/logos/logo_v2.png`
* Change the folder of your file. Move, copy, or upload to another directory and use the new one. Eg. `/newLogos/logo.png`
* **Use Cache Purging. Read below.**

In order to purge caches, you have 2 options:

* By creating a new purge request through your Dashboard
* By using our [Purge Cache API](/api/api-methods/storage/purge-cache.md)

### Purge path requirements

In order to purge a file or path, your input <mark style="background-color:orange;">**should satisfy at least 1**</mark> of the conditions below

{% hint style="info" %}
imagemash will purge all of your files whose paths begin with your input. Consider your input as a search string.
{% endhint %}

1. **The `path` should be the complete path of the file.**\
   That means a valid file path and an extension should exist.\ <mark style="color:green;">Valid Examples:</mark>\
   :white\_check\_mark: `/logo.png`\
   :white\_check\_mark: `/company/logo.png`\ <mark style="color:red;">Invalid Examples:</mark>\
   :x:`/logo`\
   :x:`/company/`\
   :x:`/logo.png/`
2. **The path should be at least 15 characters long.**\
   That means it could be a complete path, part of the path, or an incomplete path.\ <mark style="color:green;">Valid Examples:</mark>\
   :white\_check\_mark: `/companies/my_company`\
   :white\_check\_mark: `/companies/my_com` (It will purge all file paths that start with this value)\
   :white\_check\_mark: `/my_image_repository`\
   :white\_check\_mark: `/my_image_repository/`\
   :white\_check\_mark: `/img.png` (Valid because it satisfies the first condition)\ <mark style="color:red;">Invalid Examples:</mark>\
   :x:`/logo`\
   :x:`/company/`\
   :x:`/company/imgs`
3. **The path should be nested in at least 2 folders.**\
   That means it could be a complete path, part of the path, or an incomplete path.\ <mark style="color:green;">Valid Examples:</mark>\
   :white\_check\_mark: `/img/big/`\
   :white\_check\_mark: `/img/big/my_` (It will purge all file paths that start with this value)\
   :white\_check\_mark: `/img/big/logo.png`\
   :white\_check\_mark: `/my_company_big/` (Valid because it satisfies the second condition)

   <mark style="color:red;">Invalid Examples:</mark>\
   :x: `/companies/`\
   :x: `/company/`\
   :x: `/company/imgs`

{% hint style="warning" %}
All users have a monthly limit of 500 cache purge requests. Please contact us if you need more limits.
