I am an accidental early adopter of Filemaker Server 19.4.1 - something I don't make a habit of.

In the release notes it gives the following information:

• Previously, FileMaker Server allowed a URL for a custom FileMaker WebDirect home page to include redirects to external sites. Starting with FileMaker Server 19.4.1, custom home page redirects are disabled by default. The redirect settings are configured in the jwpc_prefs.xml file with two new parameters: homeurlenabled and customhomeurl. The jwpc_prefs.xml file is located in [installation_folder]/Web Publishing/conf.

I found this quite confusing, perhaps due to the fact I was working late.

After connecting with Claris support and some testing I worked it out. To use https://[server url]/fmi/webd/[db name]?homeurl=[db home page] the domains must be in the allowed list in jwpc_prefs.xml. The full URL does not need to be in there.

For example:

<parameter name="homeurlenabled">yes</parameter><parameter name="customhomeurl">https://domain.com,https://anotherdomain.com</parameter>

Please note multiple domains must be separated with commas and no space. Also a reboot is required after any changes.

In the above example any URL on domain.com or anotherdomain.com would be allowed in the homeurl parameter.

Also note you cannot use a relative link to access a page on the FMS server - you must use the full domain name (or I guess IP address) in the homeurl and jwpc_prefs.xml.

 

Hope this helps others avoid confusion with this new feature.

Thanks Jaboda, for share this explanation. 👍
