Hi
I am running Apache Oracle http server 1.3.22 and I have written a jsp where
the size of the information sent in a form with the POST procedure can be
quite large: long description fields together with a long list of pathnames
of files. The POST event sends of this information to another jsp where file
uploading is done. Note that I am forced to use an older Java Runtime
environment, namely Java(TM) 2, build 1.3.1_01 as that is what is packaged
with Oracle.
The problem is that when the description and/or the list of pathnames is
very long, the jsp window just hangs (there isn't even an hourglass to tell
the user it is busy processing).
I have independently tested making very large uploads with a non-browser
java program to my Oracle CMSDK area (files in a database with metadata) and
there seems to be no limit to that.
I suspect the problem is with the size of the strings that are posted to the
next jsp, before the upload is done. In any case, uploading only starts in
the next window, so if the upload is the problem one can expect the browser
to display the next window, then in that second window hang on the upload.
However, I never get to my next window.
In addition, I also have this problem in another jsp where there is no
uploading but again, very large description fields.
I have tried manually setting the contentlength with the build-in http
response/request functions of javax.servlet.http.HttpServletRequest and
javax.servlet.http.HttpServletResponse i.e.
response.setContentLength(5000);
In fact, this does not only seem to set the size of what can be posted, but
also the size of everything showing on the page - if you set it to small,
only part of the page is displayed, if you set it too large, things appear
twice!
Setting the content length does not seem to help at all - and if you check
the contentlength without setting it first with
int contentlength = request.getContentLength()
the size of the content is automatically adjusted for the amount of
information in the page. However, over contentlength around 1500 the page
always just hangs forever.
Is there a limit to the size of the information that can be sent via a POST
event? If so, is there a place where this can be changed?
Is the limit a web server limitation, a javax.servlet.http.HttpServlet
limitation or perhaps a limitation of the browser? Most people here use
Internet Explorer.
Any help or information will be greatly appreciated.
Thanks
