# Known issues for Web - HTTP/HTML

Tip: For general troubleshooting and limitations, see Known issues.

- HTTP/3 is not supported for the Web-HTTP/HTML protocol.
- Certain POST requests may require HTTP headers which are not automatically generated in the recorded script. To add headers, use the web_add_header API function. For details, see the Function Reference.
- Port mapping configurations is not supported in the Proxy Recording mode.
- When strong private key protection is set on a certificate and the WinInet mode is used during the replay, you may be required to manually enter authentication details when replaying the script.
- When using certificates, if your script refers to the certificate by a wrong index number, such as web_set_certificate_ex("CertIndex=2", LAST), the authentication may fail.
  Solution: Regenerate the script (not for WinInet mode recording), or manually set the correct certificate index. To determine this, in Internet Explorer, open the Certificates list (Tools > Internet options> Content > Certificates) and use the order of the certificates as they are listed, beginning with 1.

- When recording a Java application with SSL, you need to install the OpenText Professional Performance Engineering CA certificate. To install the certificate:

  1. Copy the certificate file wplusCAOnly_Expiration_<year>.crt from the <installdir>\bin\certs folder, to the location of the Java keystore file, cacerts. This example assumes the typical folder, C:\Program Files (x86)\Java\jre<version>\lib\security.
  2. Rename the file to wplus.crt
  3. Open the command prompt, and go to the keystore file's folder, by typing cd C:\Program Files (x86)\Java\jre<version>\lib\security.
  4. Run C:\Program Files (x86)\Java\jre<version>\bin\keytool –list –keystore cacerts.
  5. You should see the list of all installed certificates. When prompted for a password, enter changeit.
  6. Run C:\Program Files (x86)\Java\jre<version>\bin\keytool –import –file wplus.crt –keystore cacerts –alias LoadRunnerCA --trustcacerts. When prompted for a password, enter changeit.
  7. Record your secure application.

- The NV Insights Report is not supported for 64-bit replay.
