:(

Obviously reproducability is a key ingredient to proper analysis. If
you and he are willing to do some targeted testing, you could
instrument the client and see what the difference is -- likely in the
headers -- in the response coming from the server.

It might come down to a combination of Pragma, eTag, and other headers
coming from Tomcat (or an intermediate proxy). There have been reports
of weirdness with Adobe Acrobat Reader and "Range" headers recently:
it appears that the client is only partially spec-compliant because
the server is not required to return the exact range(s) the client
requested.

too many permutations of component versions to point to any one culprit
start with a rock solid environment 
put in a ROOT.WAR that will demonstrate the aberrant
Replace each component one at a time with a test version
i would start with Tomcat APR/native connector something like this should work
working version is _  test version is ___

save the $TOMCAT_HOME\logs output for 
working environment
each component delta 
diff the catalina.*.log from test environment with working set 
diff the localhost.*.log from test environment with working set

Finally are you CERTAIN the adobe plugin is correct for the version of your 
Browser?

Is your setup using tcnative? Version 7.0.27 introduced an update

Changelog: Update the native component of the Tomcat APR/native connector to 
1.1.23 and take advantage of the simplified distribution. (mturk)

Maybe you could change your HTTP connector from protocol="http" (has some autodetection

No, we are using the AJP connector.

 


Same same but different: this one is also using autodetection.

So you should test protocol="org.apache.coyote.ajp.AjpProtocol"

Tomcat 7.x and Internet Explorer Adobe Reader plugin

[Miguel Gonzalez]

Dear all,

  Our webapp worked fine under Tomcat 5.5. We decided to migrate to Tomcat 7 to 
get better performance and get support from the community in case something 
goes wrong as suggested in this mailing list.

  I installed tomcat 7.0.29 from the Apache website. I had issues downloading 
PDFs from IE, but not from Firefox or Chrome.

  I googled a little bit and some people suggested to downgrade to 7.0.26. But 
still having issues with it under IE while it works under Firefox and Chrome.

  Any ideas?

  Regards,

  Miguel
