Have a picture on a remote web server. Picture updated every 30 seconds. When I try to pull this picture via http link. ignition designer shows me some pictures stored in cash on the gateway. I can see on http server-side, the gateway is asking request this picture all the time when i try, but showing the same what he receives on a start.
there is some a way how to push update picture in a project?
When i try to binding HTTP, ignition trying read picture like a text and designer is frozen tottaly.
Try adding a Cache-Control: no-cache
http header, if you’re using an HTTP binding:
If you’re using the image component’s
source
property directly, you aren’t able to set this header
here is how it looks.
web page what i try to open via picture
<html>
<head>
<title>Index</title>
<meta http-equiv="refresh" content="30">
<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />
<meta http-equiv="Cache-Control" content="max-age=0"/>
</head>
<body>
<img src="/static/images/screenshot.png" alt="desk 1">
</body>
</html>
if i put link in source http:\10.100.100.180
it not show me any picture
for this link i have a picture http:\10.100.100.180\static\images\screenshot.png
but it always from cash on gateway side
i try setup it via binding
even if i add link to source too, it show me error.
