See also the [corresponding UX guide](https://design.gitlab.com/#/components/modals).
We have a reusable Vue component for modals: [vue_shared/components/gl_modal.vue](https://gitlab.com/gitlab-org/gitlab/blob/master/app/assets/javascripts/vue_shared/components/gl_modal.vue)
Here is an example of how to use it:
```html
<gl-modal
id="dogs-out-modal"
:header-title-text="s__('ModalExample|Let the dogs out?')"
footer-primary-button-variant="danger"
:footer-primary-button-text="s__('ModalExample|Let them out')"
@submit="letOut(theDogs)"
>
{{ s__('ModalExample|You’re about to let the dogs out.') }}
The DAST job can be run anywhere, which means you can accidentally hit live web servers
and potentially damage them. You could even take down your production environment.
For that reason, you should use domain validation.
Domain validation is not required by default. It can be required by setting the [environment variable](#available-variables)`DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` to true.
```yaml
include:
template:DAST.gitlab-ci.yml
variables:
DAST_FULL_SCAN_ENABLED:"true"
DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED:"true"
```
Since ZAP full scan actively attacks the target application, DAST sends a ping to the target (normally defined in `DAST_WEBSITE` or `environment_url.txt`) beforehand.
If `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` is false or unset, the scan will _proceed_ unless the response to the ping
includes a `Gitlab-DAST-Permission` header with a value of `deny`.
If `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` is true, the scan will _exit_ unless the response to the ping
includes a `Gitlab-DAST-Permission` header with a value of `allow`.
Here are some examples of adding the `Gitlab-DAST-Permission` header to a response in Rails, Django, and Node (with Express).
##### Ruby on Rails
Here's how you would add a [custom header in Ruby on Rails](https://guides.rubyonrails.org/action_controller_overview.html#setting-custom-headers):
Here's how you would add a [custom header in Django](https://docs.djangoproject.com/en/2.2/ref/request-response/#setting-header-fields):
```python
classDastWebsiteTargetView(View):
defhead(self,*args,**kwargs):
response=HttpResponse()
response['Gitlab-Dast-Permission']='allow'
returnresponse
```
##### Node (with Express)
Here's how you would add a [custom header in Node (with Express)](http://expressjs.com/en/5x/api.html#res.append):
```javascript
app.get('/dast-website-target',function(req,res){
res.append('Gitlab-DAST-Permission','allow')
res.send('Respond to DAST ping')
})
```
##### Domain validation header via a proxy
It's also possible to add the `Gitlab-DAST-Permission` header via a proxy.
###### NGINX
The following config allows NGINX to act as a reverse proxy and add the `Gitlab-DAST-Permission`[header](http://nginx.org/en/docs/http/ngx_http_headers_module.html#add_header):
```
# default.conf
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://test-application;
add_header Gitlab-DAST-Permission allow;
}
}
```
###### Apache
Apache can also be used as a [reverse proxy](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html)
to add the Gitlab-DAST-Permission [header](https://httpd.apache.org/docs/current/mod/mod_headers.html).
To do so, add the following lines to `httpd.conf`:
[This snippet](https://gitlab.com/gitlab-org/security-products/dast/snippets/1894732) contains a complete `httpd.conf` file
configured to act as a remote proxy and add the `Gitlab-DAST-Permission` header.
