<body>
<div class="container-fluid">
{{ template "header" . }}
<div class="row">

Parse all templates when starting the router.
router.LoadHTMLFiles("templates/main.html", "templates/userregister.html", "templates/userprofile.html")
Then in your handler add to the gin.H{ ... } expression a boolean variable, eg "isLoggedIn" , and then in your main template use an if-else action together with the template action.
{{ if .isLoggedIn }}
{{ template "userprofile" . }}
{{ else }}
{{ template "userregister" . }}
{{ end }}
