global.asa fires after url parameters?

When clicking on the following link from an email i.e -
http://myserver/myapplication/myprog...2=more%20stuff
I get a server 500 error. With that same browser window open, if I click
the link from the email again I get the desired page. The results are the
same if the url is copied and pasted into the brower but the 'go' must be
pressed twice.

It appears that the server is trying to resolve the url vars before the
global.asa is fired. Does anyone know of the order of processing? Any
suggestions?

This is a emailclient cum browser issue, IMHO

global.asa does not fire every time a page is called, only at a [re]start
of the server/IIS.

Why do you think global.asa has anything to do with it?
Try the same without any global.asa present.

E: This is a emailclient cum browser issue, IMHO
W: I don't believe this is an emailclient issue. I can create the problem
without email. If you start a new browser and paste the url with the
urlvariables then the error occurs. The page requires the URL variables to
locate the specific recordset from the database and the session must be
started prior to that to establish connectionString, who you are, your
security, and more.

E: global.asa does not fire every time a page is called, only at a [re]start
of the server/IIS.
W: It fires every time I open a new browser and call my application. It
starts a new unique session for each browser conversation with the
application. This is only an issue if a session is not established.

E: Why do you think global.asa has anything to do with it? Try the same
without any global.asa present.
W: My app won't work without global.asa present. I rely on many session
vars for db connectivity and resolving security.

W: I think it is global.asa since the first time I type in the url and press
'go' or enter I get the error but the second time I press 'go' or enter the
page is delivered correctly. I think on the first trip to the server, the
server 1) attempts to resolve the url vars first, 2) then processes the
global.asa, 3) then attempts to deliver my page but my url vars are no longer
available. On the 2nd trip to the server, the session was established in the
1st trip and now the url vars are resolved correctly.

I am still in search of the order of processing by the server for an asp
request.

Application_OnStart fires only when your application starts, that is
generally only the first time a page is requested after you have made
changes to global.asa.

Session_OnStart is caled once when a new session starts. This means, if
you browse the site, Session_onstart is only called the fist time you go
to the first page.

A new session might start when you start another webbrowser but I guess
that is a settings thing?

Anyway, I am still in search of the order of processing by the server for an
asp request.

The url vars are never automatically resolved.

If it is a new session, session_onstart is called first, in there you
might resolve the url vars with request.querystring if you want.

When session_onstart is ran to the end (or imediatley if this is your
second request) your asp page will be compiled and run from the top to
the bottom.

If you post the content of your global asa and myprogram.asp I am sure
it will be much easier to spot the error.

Dear waterbug,

Tim is right. [also on the quoting issue, but that aside]

The fact that Session_OnStart is called at the beginning of every new
session does not mean that global.asa is run. Global.asa runs only at
the application start. Session_OnStart sub is helt in memory.

I suppose your problem is a session problem. If the session is not helt,
because the browser does not allow a ram-cookie, every page is a new
session with a new call to the Session_OnStart sub. ASP pages are always
a session.

However without relevant code we cannot envision the exact nature of
your problem.

btw, did you try to debug?

========================
I rely on many session vars for db connectivity and resolving
security.


And you initialize those session variables [we are talking session() ?]
in Session_OnStart?

Why?
They can more easily be initialized on your entry page, easying the
debugging process. Or if you have multiple entry possiblilities, with a
include statement.

That way you can have administrative entry using a different security
appoach for your own purpose. Or differnt [open?] pages in another part
of your site.

Let me try to rephrase my problem. On a page call that invokes a new unique
application/session, the included query string (URL parameters) that are
passed are trashed, ignored, stripped (however you want to say it). Is it
true that the server's asp process will ignore URL variables if the page
invokes a new session? Is it impossible to refer to URL parameters on the
page that starts a session. It appears I am unable to refer to URL
parameters in an asp page that invokes a session.

Create a small page (or set of pages) that illustrates your problem. This

You can. IMO the problem is rather that you have some error in your
global.asa file having then an error just when the session starts...

You should start by disabling simplified HTTP errors to that you can clearly
see what this 500 error is exactly...

I have recreated a project in Visual Studio 2003 and everything works fine
when there is no global.asa. When I add a global.asa that does very little
or an empty global.asa then the page url variables are not recognized during
the first load. The behavior is again demonstrated that only during the
second load does the query_string get recognized. Can one of you add an
empty global.asa in your project to see if this 'breaks' it? Thanks...k

No problem here. What if you use Request.QueryString ?

Try also with an emply global.asa (rather than with doing a minimal amount
for things we have no idea about).

Are you sure this is not a cache issue ?

Don't make us guess what you mean by "empty global.asa". Post the global.asa
