Glimpse running but not showing up

[Vincent Courcelle]

Hi,


I've installed Glimpse, but I can't make it appear (YES I did click on "turn glimpse on" and the message "Glimpse cookie set 'On'When you go back to your site, depending on your policies, you should see Glimpse at the bottom right of the page." appears on Glimpse.axd).

I'm running locally (using IISExpress).

I've a custom security policy: the policy runs correctly (I can see it when I put breakpoints in it). I tried to disable it or always returning RuntimePolicy.On but still nothing showing up.

By not showing up I mean I don't have the little "glimpse" box and nothing in the source code of the pages matching "glimpse".

I tried:

- uninstalling glimpse nuget packages and reinstalling, leaving the web.config as the package make it

- using another browser (initially no cookies)

- when I first tried glimpse few weeks ago it was working just fine, but I had to disable it for security consideration (I didn't had an auth provider at the time). I made many changes to the website since then, but I can't understand what's interfering.

Here is my web.config:

Thanks for your help!

Sorry, I forgot to mention: I'm running ASP.NET MVC4 (correct packages are installed, Glimpse Core+Glimpse ASP.NET+Glimpse Mv4)

[Vincent Courcelle]

Solved! <urlCompression doStaticCompression="true" doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> was causing the issue...

[Nik Molnar]

Sorry you had to work through that yourself Vincent.

You can use urlCompression if you want to, you just have to give Glimpse a little bit of help.

Here's the info you'll need: http://getglimpse.com/Help/Troubleshooting

Thanks,
Nik

Hi Nik!

Thanks for the link!

I tried it and worked... almost like a charm. In fact when the entire page is not "cached" (ie no "[OutputCache]" on the controller's action), it works perfectly.

Things get tricky when using (full page) caching (not only when using compression+snippet): I'm using a Custom Policy (see http://pastebin.com/EGgENb8N

 ) that uses the Session to cache the fact the users can or cannot access Glimpse. But when the page is cached, the Session accessed in GlimpseSecurityPolicy is in fact the ORIGINAL session (I think the session that put the page in the cache or something). This is very dangerous as it can easily be unnoticed while leaving a huge potential security hole.

2 browsers, same Session (including session's id), first time I ever see this ^^ I haven't looked deeper, but it might be the entire httpContext which is the same -- even worst, because it wouldn't allow any custom auth on Glimpse if pages are cached (cookies based auth).

 

Cordialement,

Hi again Nik,

On the troubleshooting page you sent me, it's unclear if I need to put dynamicCompressionBeforeCache to false in any case or only not to have to insert the snippet "@Html.GlimpseClient()". In my case I left dynamicCompressionBeforeCache="true" and inserted the snippet in my _Layout page.

Here is the full quote of the page http://getglimpse.com/Help/Troubleshooting :

One possible scenario where HTML content is compressed is by using IIS URL Compression. One way this can be enabled is from the following Web.config setting:

<system.webServer>
  <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" />
</system.webServer>

In this case, to get glimpse working you would set the value of the dynamicCompressionBeforeCache attribute to false.

For projects using ASP.NET MVC, add the GlimpseClient HtmlHelper to the end of the view or layout:

@Html.GlimpseClient()

 

Cordialement,
Vincent Courcelle

Hey Vincent,

You can always use the @Html snippet without worried.

If the compression is set to false Glimpse will auto-inject the @Html snippet for you.

So all in all, it's always safe to use @Html and will resolve the issue for you.

Thanks,
Nik
