We have a signage (xibo) and whoever creates/changes content, likes to
add
URLs of some webpages there. All works well if these are webpages on our
servers (which are pretty fast), but some external servers often take
time
to respond and take time to assemble the page, in addition these servers
sometimes get really busy, and when response is longer than time devoted
for that content in signage window, this window hangs forever with blank
white field until you restart client. Trivial workaround: just to get
snapshot (as, say daily cron job), and point signage client to that
snapshot definitely will solve it, and simultaneously we will stop
bugging
other people servers often without much need for it.
But when I tried to search for some utility or script that makes webpage
snapshot, I discovered that my ability to search degraded somehow...
many/most webpages these days are heavily dynamic content, a static
snapshot would likely break. plus any site-relative links on that
snapshot would be pointing to your server, not the original, any ajax
code on that webpage would try to interact with your server which won't
be running the right back end stuff, etcetc.
I usually am not good at explaining what I need. I really only need an
image of what one would see in web browser if one point to that URL. I do
not care it to be interactive. I also don't want to get the content
("mirror") of stuff that URL points to on variety of "depths" - I don't
want to use wget or curl for this reason. That is what I tried first and
it breaks with at lest one of the web sites - they do seem protect
themselves from "robots" or similar. And we don't need it. We just need to
show what they page shows today, that's all.
