Hi All,

I try to post data on a web site, and for some reason the server reject my 
post (internal server error 500). I used a sniffer and I can compare the 
data sent by Internet Explorer and I notice it contains some empty 
variables.

I tried to send the variables from Indy like this:

ParamData->Values->["MyVariable"] = "";

but Indy actually doesn't send "MyVariable" at all if it sees it is empty. 
Is there a way of "convincing" Indy to send it anyway?

I use Indy 9.0.17, if that matters.

Any response appreciated.

Regards,
Nicolae

Please show your actual code, and the actual data that both Indy and IE are
sending.

Assigning an empty string to a TStrings class via the Values[] property
removes that value from the list.  That is a Borland idiom, not an Indy one.
If you need to send blank values, then you need to use the Add() or Insert()
method instead of Values[], ie:

    ParamData->Add("MyVariable=");

Hi Remy,

Thank you very much for your support. The question I had was only related 
with posting the empty variables, and your advice, to use

ParamData->Add("MyVariable=");

worked as expected.

Best wishes,
Nicolae
