## Template
Template is a YAML input file which defines all the requests and
 other metadata for a template.




<hr />

<div class="dd">

<code>id</code>  <i>string</i>

</div>
<div class="dt">

ID is the unique id for the template.

#### Good IDs

A good ID uniquely identifies what the requests in the template
are doing. Let's say you have a template that identifies a git-config
file on the webservers, a good name would be `git-config-exposure`. Another
example name is `azure-apps-nxdomain-takeover`.

```yaml
# ID Example

   kval contains the key-value pairs present in the HTTP response header.
   kval extractor can be used to extract HTTP response header and cookie key-value pairs.
   kval extractor inputs are case-insensitive, and does not support dash (-) in input which can replaced with underscores (_)
 	 For example, Content-Type should be replaced with content_type

   A list of supported parts is available in docs for request types.
 examples:
   - name: Extract Server Header From HTTP Response
     value: >
       []string{"server"}
   - name: Extracting value of PHPSESSID Cookie
     value: >
       []string{"phpsessid"}
