URL parameters stripped on Google Sites?

Question

Using Google Apps Script gadget, I can use the parameters of the URL (http://sites.google.com/.../my-page?urlparameter=value&otherurlparameter=value) added to a Google Sites webpage to generate dynamic content.

But if you try to add a link to a page of a Google Site with parameters, and then save your page, the parameters are deleted : http://sites.google.com/.../my-page?urlparameter=value&otherurlparameter=value becomes http://sites.google.com/.../my-page. Same thing when trying to publish a webpage using Apps Script Service SitesApp.Page.setHtmlContent(yourHmtl).

It doesn't happen when using external URLs. How can we bypass this limitation ?

Answer 1

It's possible to include relative links to pages including parameters.

Example : in http://sites.google.com/.../home/page-1, a link like http://sites.google.com/.../home/page-2?urlparameters will be overwritten without parameters but ../page-2?urlparameters won't be.
