Subject using back button on the browser
Date Thu, 27 Jul 2000 12:29:17 GMT
Hi, all.
I am using cocoon to produce pdf from xml. I can get the pdf correctly.
However, after I refreshed this pdf screen several times then click the back
button on the browser, I see stuff like this:

%PDF-1.2 1 0 obj << /Type /Catalog /Pages 2 0 R >> endobj 2 0 obj << /Type
/Pages /Count 0 /Kids [18 0 R 20 0 R ] >> endobj 3 0 obj << /Type /Info
/Producer (FOP 0.12.1) >> endobj 4 0 obj << /Font << /F3 5 0 R /F2 6 0 R
/F1
7 0 R /F12 8 0 R /F11 9 0 R /F10 10 0 R /F9 11 0 R /F8 12 0 R /F7 13 0 R /F6
14 0 R /F5 15 0 R /F4 16 0 R >> /ProcSet [ /PDF /ImageC /Text ] >> endobj 5
0 obj << /Type /Font /Subtype /Type1 /Name /F3 /BaseFont /Helvetica-Bold
/Encoding /WinAnsiEncoding >> endobj 6 0 obj << /Type /Font /Subtype /Type1

/Courier-Bold /Encoding /WinAnsiEncoding >> endobj 10 0 obj << /Type /Font
/Subtype /Type1 /Name /F10 /BaseFont /Courier-Ob..............

only after I click the back button again can I go back to the original
page(that is, the page that has a link to the pdf). If I do not refresh the
pdf screen and click the back button, the above stuff won't show. It's ok. 
It really puzzled me. some one has idea how to get around this? 
Helps greatly appreciated.
