Passing huge string parameters through WebTier app

rbuser

Hi!

Here's my case :

I have an app that is my ReportServer (it has many forms with many ppReport
registered in RBServer catalog).

Then I have a WebTier dll (ServerReportWebTier.dll) registered in IIS. This
WebTier is conected to the ReportServer app.

And I have a IntraWeb app that has a form that has a button that calls a
report from the WebTier app.

To call the report I'm using the following URL :
http://localhost/Test3/ServerReportWebTier.dll/RAAtiv?content=viewer&volume=Relatorios&name=Areas de Atividade&zoom=100&folder=v0&InitialDate=01/01/2004&SomeCode=123

In this call I must pass many parameters and one of them is a SQL Where
clause that may have many chars (in tests I found a Internet Explorer limit
for URL size that is about 1800 chars).
In some cases my URL will be greater than this limit.

So, I ask : is there some other way to pass these parameters (this huge
string that is a piece of a SQL statement) ?

TIA

You need to use an HTTP Post method rather than a Get method. A Get method
has a length limitation, but a Post does not.

Typically a Post method is used to submit a form.

The WebTier's AutoSearch forms use a Post. Here is an example taken from our
live server demo. (You can view this in your web browser by running one of
the autosearch reports in our demo and performing a view | source on the
AutoSearch form displayed in your browser).

Hi, thanks Nard for the answer.

In fact, I'm using this code on Onclick event of a Button (remenber this
button is on a IntraWeb app) :

AddToInitProc('NewWindow(''' +
'http://localhost/Test3/ServerReportWebTier.dll/RAAtiv'+'REST OF MY HUGE
URL''', ''MyWindow'', '''');');

But the way u is proposing seems to be better.

How can I use the way u told me ? Where exactly I must put this piece of
code of your exemple (something like that) ?
I'm not using AutoSearchParameters (because I thought to pass my params in
the URL the way I did before would be more easy). But if u think it's better
to use AutoSearchParams, I'll try, and of course, would be more easy if u
give me some guidelines, tips, etc. :-)

By the way, whats the main differences between these two ways I can pass
params ?

Thank you very much

You are really asking an HTML/HTTP question. HTTP supports types of
requests, HTTP Get and HTTP Post.

1. Here is an example of a Get

http://www.digital-metaphors.com/rbWebPub/Report.dll?myFirstParam=One+mySecondParam=Two

So we have a URL followed by a '?', followed by the parameters.

2. An HTTP Post can be issued from HTML by using an HTML Form. Example:



When a Form is submitted all of the form input elements are sent to the web
server as part of the request. You can define Hidden input elements to send
parameters.
