I have a lead gathering form on my website. I currently use it to gather leads for my clients as follows:

1. User fills out form
2. Form data is validated by form processing script on my server (java based validation)
3. Form data is posted to form processing script via http://mysite.com/myformprocessingscript/etc
4. My form processing script saves the lead in a database, so I can review and count the leads generated and then it emails the form data to the client.
5. A confirmation page from my site is shown.

However, I have a new client that does not want to receive his leads via email. He wants me to post the form data directly to his website as a query string:

http://hissite.com/hisformprocessor?formfield1=#*$!_formfield2=yyyetc

Unfortunately, I don't know how to code this. Can someone give me some ideas that may meet the following criteria:

1. User fills out form.
2. Form data is validated.
3. Form data is compiled into a query string and posted to clients site.
4. Somehow, form data is also sent/saved for me to review, as well.
5. Confirmation page from my site is shown.

Hopefully, there is an existing form processor/script!

Thanks!
