Hi to all,

I am trying to send a string value from my application to java servlet using HTTP api
like
//eg "sulabh#04"
TBuf<40 > iName;
iName.Append(username);
iName.Append(_L("#"));
iName.Append(password);
iFormEncoder->AddFieldL(KPostParamName, iName);

but when i recieve this on servlet side it becomes "sulabh%2304"
I am not getting what is the reason behind this.

Please tell me what is wrong with this

Thanks in Advance

I don't think there is anything really "wrong" with it.

Part of the HTTP standard or URL standard or whatever (I'm no web guy) says you translate "special" characters to that %-form.

Your servlet should be able to handle it and translate it back.

Re: strange behaviour of Descriptor

You probably can't prevent this from happening, as it is indeed a requirement of the relevant Internet standards that special characters like # are encoded as %23.

I think you have 2 choices: Prevent this from happening by simply not using such characters for the strings that you send (difficult, maybe impossible), or decode the strings on the server side (probably trivial, maybe done with just one method call).

Re: strange behaviour of Descriptor

You mentioned that you work with Java Servlets.

Well, this tutorial here that a quick Google search turned up mentions that % problem and says that the servlet methods all handle this automatically:
http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/

So I wonder where you run into problems?
