A little something about everything

So you open up F12 and see this obscure error:

What now?

In some cases this is caused by browser updates or perhaps server changes like adding gzip support to IIS.

This error in most cases is to to some code not properly closing before another script is executed thus chunking the response.

You should review the code for the page and look for Response.Close(); method. Something like this:

and replace it with a proper Response.End(); method instead.

Now save and reload your page.

First if you have not yet done so enabling dynamic compression on IIS improves page load speed by about 300% in most cases. To do so you can follow the following steps.

From Server Manager choose "Add Roles and Features"

Now Next on the before you begin page if you have not already checked the box for "Skip this page by default" option previously.

 Leave the default of "Role-Based or feature-based installation" selected and choose Next.

Now expand "Web Server (IIS)", "Web Server", "Performance" and check the box for "Dynamic Content Compression" then choose Next, Next then Install.

Now you're done.

In some cases some older code can cause you issues after doing this. For example some .net code previously written to use Response.Close(); method will toss a net::ERR_INCOMPLETE_CHUNKED_ENCODING error in Chrome and Edge Chromium browsers.

You can solve this with the following method.

How to solve the net::ERR_INCOMPLETE_CHUNKED_ENCODING error.
