Jag,
There seems to be some misunderstanding about what http-webtest can test
and what it can not. The sole purpose of this test framework is to
monitor the behaviour of http webservers and applications that are
accessible throug http (like PHP, CGI, Servlets and such). Hence the
name "HTTP-WebTest".
Now what you are looking for has more to do with http client behaviour
(the web browser).
What happens when a user clicks the "back button"?
This largely depends on:
1. caching headers sent with the original http document (the web page)
2. browser settings (Always compare with server /sometimes /never compare).
3. intermediate proxy behaviour (inspection of query and headers)
The first item *can* be tested by HTTP-WebTest (you have to look for
specific headers like last modified timestamp and caching headers),
other items are of course beyond the purpose of the framework.
However, as you can even construct the headers which WebTest sends with
the page request, you could as well generate a "if-modified-since:
<timestamp>" header on the fly and see what happens.
The conclusion has to be that you can accurately monitor what the web
document the server is returning to you depending on lots of conditions,
but you can not mimic the behaviour of user agents AKA "browsers".
HTH!
Cheers,
Joe.
