E2E SAP RESTifier 2.0Since SAP RESTifier version 2.0, the proxy must change the base href in all HTML files, if you run the RESTifier behind a transparent proxy. For earlier versions of the RESTifier, this is not necessary, because they have relative URLs.

In the HTML file you have the href attribute of the base tag:

Code Block
languagexml
<base href="/">

You have to add your proxy URI path prefix here. If your proxy has e.g. the URI path prefix /saprestifier, the proxy has to change the base tag to:

Code Block
languagexml
<base href="/saprestifier ">

Configuring your Apache proxy, you can use the following rule to add the prefix:

Code Block
AddOutputFilterByType SUBSTITUTE text/html
Substitute "s|<base href=\"/\">|<base href=\"/saprestifier/\">|i"

Example Apache Configuration

Find below an example Apache configuration for two parallel SAP RESTifier installations:
