G'day fellow iText users.
I have recently joined the long list of web page developers battling
with the IE bug/feature that causes the "cannot write to cache" error
when downloading PDF files from one of my sites.
I realise that this is not really an iText issue but iText users have
obviously spent a lot of time trying to find a work-around and might be
able to help me.
I have tried all of the suggestions that I can find but with no avail.
The critical part of the scenario at this particular site seems to be an
IChains server that converts all HTTP traffic to HTTPS. There is no way
that the site will allow me to bypass that box.
As part of it's processing of (at least iText generated) PDFs, it seems
to add a Pragma: no-cache header which in turn causes IE to barf.
The interesting thing is that I can download previously created PDF
files from this site without any problem - but with slightly different
code.
Can anybody please explain why the following two code snippets should
give such different results?
Cheers and thanks,
Stephen Davies
PDF file code:
bfile = new java.io.File(sid);
blob = new java.io.FileInputStream(bfile);
httpservletresponse.setContentType(s1);
httpservletresponse.setContentLength((int)bfile.length());
ServletOutputStream servletoutputstream =
httpservletresponse.getOutputStream();
byte abyte0[] = new byte[8192];
int l = blob.read(abyte0);
if(l == 0)
{
return;
}
servletoutputstream.write(abyte0, 0, l);
while((l = blob.read(abyte0)) != -1)
servletoutputstream.write(abyte0, 0, l);
iText PDF code:
PdfWriter.getInstance(doc, baos);
doc.open();
.....
doc.close();
httpservletresponse.setContentType("application/pdf");
httpservletresponse.setContentLength(baos.size());
ServletOutputStream pout =
httpservletresponse.getOutputStream();
baos.writeTo(pout);
pout.flush();
