World: r3wp

but chrome is not executing the rsp script ... as far as I can see.

I think I'll just stick with putting a time stamp on each request 
to foil the cache

Or just stick with FF / IE.

then this has nothing to do with cheyenne, add something like
join %? checksum form now/precise ad the end of requested url

if it is the rsp script that doesnt get executed , please paste headers 
from rsp response

?t= url-encode form now/time/precise

which rsp response?

you said "but chrome is not executing the rsp script ... as far as 
I can see."

yes, I put a ?? in the script and it doesn't log.

so that is the rsp you request that generate the file and upload 
it to google

yes

I'd like to see the response headers of that request , not those 
from requesting the uploaded file

thi sis the link http://gchiu.no-ip.biz:8000/md/creategoogledoc.rsp?gdoc=simple-letter.rtf&patientid=2832&encounter=none

but the page does not get executed

I can't go past http://gchiu.no-ip.biz:8000/md/login.rsp  8)

When I click on that link ... it supposed to execute a script when 
then sets the response/redirect

so there is no response from cheyenne .. only from google

with a redirect and wireshark, u should see both response headers, 
your browser is requesting two resources, one form Cheyenne, one 
from the redirected url

You'd think so .. but the pcap dump is only showing the googledocs 
response

if u private msg me a login/pas I can give it a look

impossible, that is not how it works, cheyenne responds with a redirect, 
that is an answer and has a header, the the browser request the redirected 
url from google server

I need to see headers of the redirect response sent from Cheyenne, 
the problem may be there, if that response hasn't proper Expire, 
etc.. headers it may get cached by Chrome, and thus the behaviour 
u see

this is the request

I need the response not the request 8)

Yes .. I know ... that was the end of the "follow tpc stream"

umm.. now that sessions are bound to ip I can't hijack your session 
to check that out ;-)

got to go, either paste here response headers from cheyenne or private 
msg me a temp user/login. in the meantime just add a timestamp parameter 
to the response/redirect url

timestamp also for the rsp url

userid/pass Guest/Guest

You won't be able to create a googledoc though as it requires that 
your google credentials are stored!

My reported problem: Doc, I'm not using VALIDATE nor do I check the 
parameters. Do I have to? I thought Cheyenne does this implicit.

I expect the problem with the parameter to force the seen side-effects. 
So before going into deeper analysis I want to fix the parameter 
problem. Any guide how to handle parameters correctly?

Robert, how can Cheyenne know that "quantity" must be an integer! 
value if you don't tell it? Cheyenne can't validate that implicitly, 
you have to either use VALIDATE (see API doc) or make your own checking 
routines. By default, all your GET or POST  parameters are treated 
as string! value. If you need to check for their presence or need 
to convert them to another datatype, you have to validate the format 
so that it doesn't error out (or worth, let an hostile request pass).

I've created a dummy google account so that people can try this out

pm me if you want to try ...

Conclusion, as you can see above google response for redirection 
include no caching, expires, etc,, headers, Cheyenne don't. I suppose 
that is why you don't see the second hit on your Cheyenne instance, 
Chrome is caching the Cheyenne redirection.

in the rsp that send the the 301 redirect, add this lines:

response/set-header 'Cache-Control "private, max-age=0"
response/set-header 'Expires "-1"

if that is not enough, try with this:


response/set-header 'Cache-Control "no-cache, no-store, max-age=0, 
must-revalidate"
response/set-header 'Pragma "no-cache"
response/set-header 'Expires "-1"

now try that and tell us if you see hitting your server at every 
requests

Nenad, should a redirect send no caching headers by default?

Maybe yes for a 301 and no for a 302? Personally I like it as it 
is, I can always add them when needed.

That first redirection is an authentication request from google so 
it looks like you might not have been logged in to gmail at the time. 
 I used your second suggestion and that seems to work fixing the 
caching issue.  Good work!

No wonder I wasn't seeing the response from my script ...

Anyone see why this doesn't work 

grab-cookie: func [  login-url [url!] username password
    /target web-app-url [url!]
    /local page auth cookie err
][
    if error? set/any 'err try [
        page: open login-url
        cookie: page/locals/headers/set-cookie
        close page
        auth: rejoin [ "login=" username "&pass=" password ]

        page: read/custom login-url compose/deep [ POST (auth) [ cookie: 
        (cookie)]]
        either target [

            page: read/custom web-app-url compose/deep [ GET "" [ cookie: (cookie)]]
            return page
        ][ return cookie  ]
    ][
        mold disarm err
    ]
]   


I can see it sending the cookie after authentication to get a page 
in a web-app, but I get redirected to the login age

I was logged in, otherwise I would have been redirected to the login 
page.. Good that it fixed your issue, did you try solution one, if 
not, could you please? thx

That is just how the google's auth framework works..

Response/redirect returns a code 301 by default (means "Moved Permanently"), 
that may be the cause of the unexpected caching by the browser. Could 
you try using response/redirect/temp instead?
