TRtcISAPIServerProvider - ServerVariable function

[roman.vitek]

Is there any chance to use function: TRtcISAPIServerProvider.ServerVariable() from ISAPI application ?

I have problem with server variable AUTH_USER (for automatic login). I found that in TRtcISAPIServerProvider.ExecuteRequest is this: s:=ServerVariable('ALL_RAW',8192); but when I used: login := Request.Value['AUTH_USER']; threre is nothing. In my old code I used TISAPIRequest.GetFieldByName('AUTH_USER') which return correct value.

Thanks, Roman

This is because in header value names in the ISAPI, all underscores are converted minus, to keep the code compatible with stand-alone Servers. In other words, to access the "AUTH_USER" header value, you need to use TRtcDataServer(Sender).Request['AUTH-USER']

I use RTC version 5.17 in Delphi XE so I don´t known if your answer is correct for this version too. I change RTC source code (move TRtcISAPIServerProvider.ServerVariable to Public section add and new function in TRtcISAPIServer) and this way I can call server variable form my code. And It´s working now. When I call my "GetServerVariable('AUTH_USER')" then I get correct value. But in "Request.HeaderText" there are not value for parametr AUTH_USER nor AUTH-USER. I tested this on Win 2012 + IIS 8.x.

Can you check what you get from the "ALL_RAW" server variable? I want to know if the text you get from the "AUTH_USER" variable is available there. All Request header values should be returned by the Server when requesting the "ALL_RAW" variable.

It´s the point, I found in RTC source "ALL_RAW" and I thought that server return all server variables this way. But my experiance is different: AUTH_USER is NOT in ALL_RAW but I get it with "my" new function GetServerVariable. Result: I think that MS change this in new version of IIS - may be "security reason" ?

So I think that function GetServerVariable() will be usefull in next version of RTC.

Ok, thanks for the info. A new RTC SDK update is now available (v6.29), with the GetServerVariable function exposed on the TRtcISAPIServer component. You can download it from the RTC SDK Downloads area on the Forums.
