Why Does the Page Fail to Be Refreshed After WTP Is Enabled?

Web Tamper Protection (WTP) supports only caching of static web pages. Perform the following steps to fix this issue:

1. Log in to the management console.
2. Click in the upper left corner of the management console and select a region or project.
3. Click in the upper left corner and choose Web Application Firewall under Security & Compliance.
4. In the navigation pane on the left, choose Policies.
5. Click the name of the target policy to go to the protection configuration page.
6. In the Web Tamper Protection configuration area, check whether this function is enabled.
   • If this function is enabled (), go to Step 7.
   • If this function is disabled (), click to enable the function. Refresh the page several minutes later.

7. Click Customize Rule. On the displayed page, check whether the domain name and path are correct.
   • If they are correct, go to Step 8.
   • If they are incorrect, click Delete in the Operation column to delete the rule. Then, click Add Rule above the rule list and configure another rule.

     After the rule is added successfully, refresh the page several minutes later. Then, access the page again.

8. In the row containing the web tamper protection rule, click Update Cache in the Operation column.

   If the content of a protected page is modified, you must update the cache. Otherwise, WAF always returns the most recently cached content.

   After updating the cache, refresh the page and access the page again. If the page is still not updated, contact technical support.
