I need to install and use html2PDF in a closed intranet (without internet access). Is it possible to use your service here?

html2PDF is a service that uses the internet. The service reads html files and outputs them as PDF.

You can use the following 2 parameters to render password protected pages:

HttpUsername
String, Example: user
If your page is only accessible with username/password (HTTP Authentication/Basic Authentication)

HttpPassword
String, Example: test
If your page is only accessible with username/password (HTTP Authentication/Basic Authentication)

Please see Parameters for html2PDF
