aspx-file created on the fly?

[=?Utf-8?B?RnJpdHo=?=]

hi,

i am currently investigating a bug in a complex code project. unfortunately
i cannot ask the developer having written it as he has left the company.

the thing is: a .cs-code-behind-file of an .aspx-page interacts with
client-side jscript-code. the .cs-file is sent to the client as to be seen
inside a sniffer. when taking a look at the original code one only can see
the definition of the variables. looking inside the sniffer trace one can see
that the variables are filled, coming from the settings of the logged-in
user. hereby the registry is used, but obviously a wrong key, which is
subject to be debugged.

what i do not understand: how can this be that th file.aspx, which is sent
to the client, is different to the original one, which only contains a
code-behind-dll (which itself is created from the file.aspx.cs)? in other
words: how does this work that the file.aspx is create on the fly? is there a
link describing that way of working? i was under the assumption that only
code like jscript is sent to the client...

thanks in advance, fritz

Fritz,
Most likely what you saw in the browser's "Cache" was the url to the aspx
page along with some querystring items on the url. If you right click on this
file, and copy it to another folder and then view it in your favorite text
editor you will see it contains POHTML - "Plain old HTML".

thanks, peter.

right, i know - the code is sent as html for aspx-files. but exactly this is
my problem: on one client using fiddler i clearly saw that the file.aspx
itself was in the browser´s cache. and taking a look inside the file i saw
stuff like var_a=1;var_b="abc", but not as html-code!

any explanation for me?

thanks, fritz

I think there is some confusion here. The ASPX "file" is never "Sent" to the
client.

What is sent to the client is HTML Markup, possibly containing client
script, and that is what the browser renders. Whatever the browser gets is
the RESULT of IIS processing the ASPX Page and whatever the codebehind Page
Class that it uses does.
Hope that helps.
