Wildcards are used for matching entire groups of similar URLs. For example, suppose you only want to show the Drip widget on the "/blog" subdirectory of your site. To achieve this, you need to use a wildcard.
Wildcards are denoted as either a single or double asterisk:
- * single asterisk
- ** double asterisk
Single Asterisk Wildcards
The single asterisk matches an individual URL segment. For example, the following subcategory
"/blog/*" utilizes a single asterisk wildcard. The wildcard captures the subcategory one level deeper than the one denoted. Therefore if the subcategory "/blog/" contains each blog post, the wildcard would capture "/blog/post_1", "/blog/post_2", "/blog/post_3", and so on.
Double Asterisk Wildcards
The double asterisk (**) wildcard matches one or more URL segments. For example, "/blog/**" matches "/blog/123 and /blog/category/marketing/1234" and so on.
Here are a few examples of how to mix wildcards together:
You can also use the single asterisk(*) wildcard in the query string. For example, /blog/**?s=* will match any page under the blog subdirectory with the query string parameter set to anything.
