## Symptoms

- * HTTP traffic is blocked with these errors:

  * `HTTP parsing error occurred (2)`
  * `parameters are undecodable in request`
* The kernel debug (`WS all`) shows:

  ```
  ws_http_process_http_parsing_error: Calling signature pe to process general parser event PARSING_ERROR;
  ws_http_process_http_parsing_error: *protection_scheme->extended_values[E_WS_PROTECT_ID_SIGNATURE] 0x17ffef341;
  ws_http_session_msg_read: found msg id 13;
  ws_signature_pe_general_parser_event_cb: precise error for session ffffc20029ef5030 is: parameters are undecodable in request;
  ```

* In rare cases, HTTP traffic latency is observed.

| Value of Kernel Parameter                     | Description                                                                                                                |
| ws_check_bin_param_val_on_text_content_type=0 | Security Gateway decodes all the HTTP parameters. This is the default.                                                     |
| ws_check_bin_param_val_on_text_content_type=1 | Security Gateway decodes the HTTP parameters that are ASCII-only (does not decode in case a non-ASCII character is found). |
