It depends on your needs. 1)Perhaps you can use GET requests instead of POST one. (in this case when user click on buton - it send standard asp.Net POST request on your initial site, then in button handler you collect all needed data into GET request and make Response.Redirect) 2) The same actions using client js to collect data and make redirect 3) Use iframe can help but it isn't good solution 4) Use clien-side js to remove viewstate input

Tanya,

Thanks for replying.

I am using the Get method now.  The HTML I have at this point is:

<label for="saddr">Get directions from your address:</label>
<input type="text" id="saddr" name="saddr" />
<input type="hidden" value="2144 W. Greger St. Oakdale, CA" name="daddr" />
<input type="submit" onclick="this.form.action='http://www.mysite.info/testdirections.aspx'; this.form.method='get'; this.form.__VIEWSTATE.value=' steve'; this.form.submit();" value="Go" />

The above posts the form to a test .aspx page I've set up on another site so I can see what's coming in.  (That's how I realized I was sending the 8000+ character __VIEWSTATE.)  You can see that I am using client-side JavaScript to remove ViewState input, or at least replace it with the more manageable 'steve'.  But this doesn't help. Then 'steve' is just added to the complete __VIEWSTATE.  What I see coming into testdirections.aspx then is:

http://www.mysite.info/testdirections.aspx?__EVENTTARGET=&__EVENTARGUMENT=&__LASTFOCUS=&__VIEWSTATE=+steve&dnn%24IconBar.ascx%24optMode=EDIT&dnn%24IconBa ...[+ another 8000 characters]

I'm not sure I understand what you're saying about "collecting all needed data into a GET request and doing a Response.Redirect."  Are you saying I could somehow take __VIEWSTATE out of the QueryString before redirecting to Google?
