Re: Is it possible to use data from the response header to a POST in a subsequent GET?

I'd like to do two things. Both involve constructing client-specific  
URLS.
If the second is too hard, I could probably make do with the first.

1. Client-specific urls built from tokens in a file. For example, here's
some possible syntax for the configuration file:

URL=http://a.xyz.com/users/%s/profiles/%s/subscriptions
URL_TOKEN_FILE=foo

In this case, each client would take two tokens from foo and use them  
to build the
client-specific URL.

Or, it might be simpler to build a file of complete client-specific  
URLs in advance,
and take whole URLs from the file. Maybe that could look like this in  
the config file:

URL=file("foo")


2. Build client-specific URLs from tokens returned in the body of  
previous responses.
For instance, here's a sample client-server exchange (with most  
headers omitted):

POST /login HTTP/1.1

login=gu...@in...&password=guest

HTTP/1.1 200 OK

<?xml version="1.0" encoding="UTF-8"?>
<user user_id="38" profile_id="3"/>

PUT /users/38/profiles/3/subscriptions HTTP/1.1

stuff ...

In this case I'd like to be able to grab user_id and profile_id from  
the returned
XML, and use these tokens to build the subsequent URL.
Maybe the config file could look something like this:

URL=http://a.xyz.com/login
RESPONSE_TOKEN=user_id
RESPONSE_TOKEN= profile_id

URL=http://a.xyz.com/users/<user_id>/profiles/<profile_id>/subscriptions

I realize that it would be hard to make this completely general, but  
I'm sure
I could write response-parsing code specific to my needs.


Any guidance would be appreciated!
Gary
