KB46924: 405 error "The request method POST is inappropriate for the URL /" encountered when users click an "Is Hyperlink" link to an external site in MicroStrategy Web

SYMPTOM:
 
In Strategy Web 9.4.1 Hotfix 3, users can add hyperlinks to text boxes using either the "Edit Links" feature, or the "Is Hyperlink" feature in Properties & Formatting. If using "Is Hyperlinks", customers will run into the following error when clicking on the link in Google Chrome from Strategy Web DHTML modes:

Sample Code/Error

Google
405. That's an error.
The request method POST is inappropriate for the URL /.
That's all we know.

1. Create a document in Strategy Web 9.4.1 Hotfix 3.
2. Create 2 text boxes with text inside.
3. In the first text box, right-click to go to Edit Links, and add www.google.com as the URL to navigate to.
4. In the second text box, right-click to go to Properties & Formatting, enable "Is Hyperlink", and add www.google.com as the hyperlink.
5. Execute the document in Interactive Mode. Notice that clicking on "Edit Links" navigates to the correct URL, but clicking on "Is Hyperlink" does not.

CAUSE:
 
This is a known issue in Strategy Web 9.4.1 Hotfix 3.
 
The link added to the "Navigate to this URL" portion of Edit Links executes properly. After running a Fiddler trace as per tech note KB20064,  the Request Header that is captured for Edit Links is "GET", as shown below:

 
 
The same URL from "Is Hyperlink" captures the Request Header as "POST", as shown below:

 
The link fails because the remote web site does not accept POST requests.
 
ACTION:
 
This issue has been addressed in Strategy Web 9.4.1 HF5. Upgrade to this version to take advantage of the fix.
 
WORKAROUND:
 
Because this issue only occurs in DHTML modes, users can use Express Mode to work around this issue. Additionally, this issue does not occur in Strategy Web 9.4.1 GA. Customer's can revert back from Hotfix 3 to work around this issue.
