Node icons and other images (including font icons and map tiles) that link to Web images, rather than coming from a file system, are not always displayed, due to security restrictions. Your browser will mark it as insecure and prevent the image from being loaded.
To allow the secure loading of such images, you can enable the Siren Investigate image proxy (IP) feature.
The proxy, available at
/image_proxy?url=<url> when enabled, checks if the URL specified in the
url parameter is from an allowed domain and if so downloads the image and streams it back to the browser.
If this is enabled on an unsecured Siren Investigate environment, it can act as an open relay which could be exploited. The image proxy feature is recommended for use only on a secured instance.
You can configure the proxy in the
investigate_core.image_proxy section of the
the following settings are available:
enabled: set to
trueto enable the Image proxy. Defaults to
allowed_domains: an array of strings containing domains from where images can be retrieved. Defaults to
max_image_size: the maximum image size allowed (in bytes). Defaults to
timeout: the number of milliseconds before an image request times out. Defaults to
proxy_cache_enabled: if set to
true, the proxy caches retrieved images in memory. Defaults to
proxy_cache_expiration: specifies how many seconds cached images are kept in memory. Defaults to
browser_cache_control: the value of the
Cache-Controlheader that are set in responses from the proxy. Defaults to
disable_content_type_check: if set to
true, the proxy does not block resources that are missing a
Content-Typeheader that starts with
image/. Defaults to
investigate_core: image_proxy: enabled: true max_image_size: 20000
