Hi All,

ＮｅｔＷｏｒｋ's Proxies setting, where we can put a .pac file
for proxy use.
Currently i am working in a project which will get the .pac file,
parse and
get some proxy setting from it.
So I try to find a program interface to parse a .pac file ,Anyone got
any
ideas?? Can it be done, is there a solution, simple or
otherwise.
There were very few interfaces to call upon back when I did this last
year and I'm not sure that that has changed. In the meantime, Apple has
implemented the feature as you say, and I've made my code open source.
It took some considerable development time, but I was able to build on
the open source work already done by the Mozilla team on their
SpiderMonkey engine:
<http://www.mozilla.org/js/spidermonkey/>
SpiderMonkey is Mozilla's Javascript parsing engine for C. It lets you
compile and execute Javascript source (the language of PAC files) from
within a C-compatible environment. I will now assume this is the kind
of thing you are after!
I worked with the Mozilla team to streamline the installation and
integration of SpiderMonkey on OS X and would recommend checking out
the fruits of that labour. From there, there is still some effort
involved in providing an environment for PAC files, but well, that's
what I did in my now open source program and you are free to check that
out. It's certainly not the nicest implementation possible (Mozilla
itself obviously has a very robust, sophisticated implementation) and
I'd change a couple of things if I were to do it again, but just
between you and me ;) my users tell me it is quicker than Apple's
implementation. That said, it is GPL'ed so you'd have to consider that
license if you were to use the code. Right, enough blabbing, the
software is called Authoxy, and you'll find the necessary info in the
Open Source link at:
<http://www.hrsoftworks.net>
Dumb disclaimer - I obviously have a large vested interest in that
company and its products.
Regards,
Heath
