Code:
What’s new in 3.28:
*) web proxy - allow to edit error page;

ERROR: $(status)

ERROR: $(status)


$(if error)

While trying to retrieve the URL $(url):

  • $(error)
$(endif)

Your cache administrator is $(admin). $(signature)

This is the question:
How can i change that “web proxy - allow to edit error page” ?

You must know the HTML…

The RouterOS 6.12 default “webproxy/error.html” page are:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>ERROR: $(status)</title></head>
<body><h2>ERROR: $(status)</h2>
<hr noshade size="1px"/>
$(if error)
<p>While trying to retrieve the URL <a href="$(url)">$(url)</a>:</p>
<ul><li><strong>$(error)</strong></li></ul>
$(endif)
<p>Your cache administrator is <a href="mailto:$(admin)">$(admin)</a>.
$(signature)
</body></html>

So i know html, however where is webproxy folder ?

“/ip proxy reset-html” make file and folder on /file

Thanks for fast reply.
