Troubleshooting Web Filtering
Failed to Add Filtering Entry or Suffix Keyword due to Upper
Limit
Symptom:
• When you try to add a URL parameter filtering entry, the system prompts you that no more entry can
be added.
• When you add a Java blocking or ActiveX blocking suffix keyword, the system prompts you that no
more keyword can be added.
Analysis:
The number of URL parameter filtering entries, Java blocking suffix keywords, or ActiveX blocking suffix
keywords has reached the upper limit.
Solution:
If necessary, remove some configured entries or keywords before adding new ones.
Invalid Characters are Present in the Configured Parameter
Symptom:
When you configure a URL parameter filtering entry, the system displays a character error message.
Analysis:
A URL parameter filtering entry can contain only 0 to 9, a to z, A to Z, wildcards “^”, “$”, “&”, and “*”,
and other ASCII characters with values between 31 and 127.
Solution:
Ensure that all entered characters are valid.
