If any of you webgurus has an idea to remove that barrier, then we can do much more interesting stuff

It is possible that some of the security flags for the website that we have set up recently are blocking this https://forum.freecadweb.org/viewtopic. ... 78#p174779 , we can test this by adding a hash (#) in front of individual flags to disable them, for example:

Code: Select all

#Header always set Content-Security-Policy "frame-ancestors 'none'"
#Header always set X-Frame-Options "deny"

Personally however, from security point of view, I don't really like putting all this web functionality in to FC. We are potentially giving users a very unsafe "browser" to access and browse the web with. IMO there are some possible real dangers here. IMO it is better if users browse the web from their hopefully updated browsers.

In the early times there was a "tip of the day" feature, but it stayed like, 3 years with the same five tips, so it got abandonned. All the problem is having a good and interesting source to take these things from.

One detail I don't know how to solve yet. To make the loading of the start page fast, it cannot "wait" for web content to be loaded. It must first load without any web content, then anything from the web must be fetched after the page loaded, that is, by pure javascript. However, javascript is apparently forbidden to load contents from other domains than the one it is running from. That prevents from fetching stuff from the tracker or forum. The only exception is when using the JSON format, which AFAICS none of our webapps supports, only Github (that's why I was able to fetch the commits from github).
