HttpWatch 13 is now available for download and includes the following new features.

Fully Supports Microsoft Edge

HttpWatch now works with Microsoft Edge 80 or later using an extension hosted in the Microsoft Store:

The Edge support includes an automation class for controlling the HttpWatch Edge extension:

and a sample program for using Edge, Selenium and HttpWatch together.

Enhanced Installer

You can now choose which browsers to use with HttpWatch when you run the installer. It is also possible to only install HttpWatch Studio if you just want to open existing HAR or HWL log files:

URL Indicator Symbols Show the use of  Fetch and XmlHttpRequest APIs

In Chrome and Edge an arrow symbol next to a URL shows that a request was created using the XmlHttpRequest (XHR) API in Javascript:

Or an arrow head symbol if the Fetch API was used:

Displays Service Worker Activity

When a service worker script intercepts a request the Result now displays (Service Worker). The status code is available in the data tip or Overview Tab:

A diamond URL indicator is used to show the outgoing requests made by a service worker:

Supports Snapped Window Positions

HttpWatch now restores extension and log windows to their original position even if they were placed with the Windows snap feature:

Displays SameSite Cookie Attribute

The cookie panel now displays the SameSite attribute for cookies received from the server:

Shows The Use of the Memory and Prefetch Cache

The Result column in Chrome and Edge now shows whether the memory or prefetch cache was used:

Detects The Use of JSON Without The Correct Content Type

HttpWatch now formats and applies password masking to JSON content even if the content type has been incorrectly set to a different format:

The latest update to HttpWatch includes experimental support for the beta version of Microsoft Edge (Chromium). Full support, including automation, will be added at a later date when Edge (Chromium) is officially released.

The Microsoft store does not yet support chromium based browser extensions but you can install the HttpWatch extension from the Chrome web store instead. The following steps guide you through adding HttpWatch to Edge Chromium

1. Install HttpWatch 12.1

Download and install the latest version of HttpWatch

2. Install Edge (Chromium Beta)

You can download the Edge Insider Beta Channel from https://www.microsoftedgeinsider.com/

3. Allow Edge to Install HttpWatch from The Google Web Store

Open Edge (Chromium) Beta and go to …->Extensions or enter ‘edge://extensions/’ in the location bar. Then select ‘Allow extensions from other stores’ and click Allow:

4. Install the HttpWatch extension from the Chrome Web Store

In Edge open the HttpWatch extension page at:

https://chrome.google.com/webstore/detail/httpwatch/dajhhgiioackgdldomhppobgjbinhimh

Then click ‘Add To Chrome’ which will add the extension to Edge:

Once the extension has been added you can either access HttpWatch from the toolbar icon or by right clicking on the web page and selecting ‘Open HttpWatch’.

HttpWatch 12 is now available for download and includes new features aimed at improved support for debugging JSON based REST APIs and the use of HAR (HTTP Archive) files.

1. JSON Content is Formatted & Syntax Highlighted

Single Page Applications (SPA) and other modern web development techniques make extensive use of JSON based REST calls to the server. HttpWatch 12 can now display formatted, syntax highlighted JSON request and response bodies:

2. POST Data Tab Displays Top Level JSON Data Items

Top level data items in a JSON request can now be viewed in the same way as parameters from form submits:

3. Password Masking Now Applies to Top Level JSON Values

The masking of potentially sensitive fields such as passwords now applies to JSON request bodies as well as form submits:

4. Textual Content is Displayed in a Folding Viewer

The new folding feature allows sections of text (e.g. an HTML tag) to be collapsed. This can help to simplify the structure of a file and make it easier to locate and view areas of interest:

5. Export Selected Pages and Requests as HAR

A new context menu item in the main request grid allows selected pages or requests to be saved to a HAR file instead of exporting the whole log:

6. Faster Loading of Large HAR Files

Large HTTP Archive (HAR) files now open up to 5 times faster in HttpWatch Studio.
