Troubleshooting and Limitations - Web - HTTP/HTML Protocol
This section describes troubleshooting and limitations 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_headerAPI function. For details, see the Online Function Reference.
- Port mapping configurations is not supported in the Proxy Recording mode.
VuGen cannot get a client certificate from Internet Explorer 10 while recording a session.
Workaround: Provide a client certificate in the port mapping settings.
- 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.
- In previous versions of LoadRunner, the C type "char" was considered a "signed char". In LoadRunner 11.50 and later, it is considered as an "unsigned char". If you used "char" without specifying whether it is signed or unsigned, and performed arithmetic operations on this variable, the results may be different when comparing current results with those from previous versions of LoadRunner.
