IE 6 causes broken pipe exception
Here's a followup to: Subject: DefaultServlet throws a LOT of broken pipe exceptions on mp3s. --- I found the cause of my java.io.IOException Broken pipe errors. IE 6 is sending two GET requests for each .mp3 file. I haven't tested the behavior on IE 5.x or other plugin-handled mime types. The first GET sets the request header: user-agent = contype and is a Microsoft (ie, non-standard) attempt at data-sniffing intended to get just the header information. Tomcat 4.x starts sending the content data, but IE resets/drops the connection after 30-50k (100-500 ms), generating a Broken pipe exception. IE then sends a second request for the content using: user-agent=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) which completes. [see Microsoft Knowledge Base Articles: KB 293792, KB 254337, KB 310388. Note: KB 310388 describes a fix for multiple posts in IE 6 SP1 (service pack 1). Tests from an IE 6 SP1 client however still demonstrate the multiple GETs. I'm still trying to determine if the broken pipe GET is the cause of the unreliable caching behaving I'm seeing in IE 6 (symptom: IE 6 clients are downloading about 10x vs. Netscape/Safari clients; few if any 304 responses). --- So, two questions for the karmically kind: 1) Any bright ideas on a workaround for the user-agent: contype GET? At present it's double-banging my server for 100-200k files. Is there a context level mechanism for filtering, ie, blocking, requests based on headers? 2) Is this more properly a development issue? I see workarounds in the 4.1.27 and 5.x source to ignore Broken pipe exceptions and the multiple GET is apparently rooted in kludges from browser 4.x days -- but I got no hits for user-agent contype in a google of the tomcat archives.

Can JSP track users in a basic authentication protected realm ?
Hi guys, Does anyone know how I can implement the above mentioned? Once they exit the protected realm (i.e. the protected folder in my htdocs), when they re-enter the site again they will be asked for a password. I have a simple basic authentication system but it doesn't track the user when it leaves the protected realm. What I wanted to do was to get the server to re-authenticate the user everytime he leaves my realm and tries to re-enter again. Some people suggested CGI, some suggest PHP.. I would like to know if JSP can do the job. If yes, what level of competence do I know JSP ?
Re[2]: A Hebrew Problem
Hello Yair!
Sorry about responding with such delay, I only read the list
periodically in large gulps. I'm still very interested.
YZ My Goal: including a hebrew html inside a jsp page.
YZ The Problem: hebrew is viewed by browser as question marks (no matter
YZ charset).
YZ //moving the html string to a char array.
YZ %char [] c = pageExecuter.readHtml().toCharArray();
YZfor (int i=0; ic.length; i++){%
YZ //displaying 'character code' 'character'
YZ %= (int)c[i] %;nbsp; %= c[i] %br
YZ % } %
A very correct experiment!
YZ in that way I can see in the browser each character's code and the
YZ character itself.
I'm afraid I did not understand your description.
Could you attache the whole page resulting from this experiment?
Or still better the result of
wget -s -o file.html http://your.page.somewhere/some.jsp
from this page? (I want to see the Content-Type that gets
generated, the codes you get from the (int) conversion and
wether the byte(s) generated by %= c[i] % are really question
marks (0x3F) or something else.) Again attaching the result
of wget would be better then any description.
Thanks for interesting food for investigation, Yair! :-)

Hello Hans!

HL same result What result? What codes do you get for non-ascii characters on Unix and on Windos boxes from this test? HL I have even tried HL Reader reader = r.getCharacterStream(field_name); HL and then printing out the the char values of the stream I guess r is of the type ResultSet (sorry, Chris Rolfe, you seem to have misunderstood somthing). Okay, I beleive there is not any difference between ResultSet.getString() and ResultSet.getCharacterStream(), it will be enough to test either of them HL Its the most bizarre thing i have seen.

RE: Can JSP track users in a basic authentication protected realm ?
Actually I do not know how to do it. I know those internet banking sites does it. They have this option of Log out for their users. When users click on that log out option, they will in effect log out of the protected realm. Should they decide to return to the same site again ( using the same instance of the IE) they will prompted for the password and ID again. Currently, with basic authentication ( implemented using HTTP SERVER) the server does not recognise if the user has moved onto another site outside the protected realm. If he decides to surf an area outside the protected realm, and decides to return to the protected realm, he will not be prompted for a password. This problem arise when the computer being used to access my protected realm is a public computer. If that is the case, users who enter my protected realm and forgot to terminate that instance of the IE is going to allow subsequent users of that machine to access my site. My question is how can I implement such a way as mentioned above ? The log out button kind of effect. Many thanks.

This is probably something simple, but I can't seem to understand this. As suggested by a Tomcat book that I have, I gave the webapps folder rwx to the owner, and r access to everyone else. However, when I try to change to the webapps directory as any user other than the owner I get a permission denied. Shouldn't I be able to at least view whats in this directory? Thanks.

Some help with jk2
Hello all. I'm trying to setup jk2. Well, actually, I'm trying to acquire build jk2. This is proving to be more than a little difficult. After going over the docs at http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/doc/index.html I think I'm more puzzled than when I started. And that's even discounting the broken document links, and the link to the mailing list archive that hasn't been accurate in more than a year! So I have some questions. 1) Is there anywhere where I can actually download a full version of the source, with required libraries, or at least a list of what else needs to be downloaded. Because the link to the src from the FAQ sure doesn't meet these requirements. 2) Whereas I know the difference between jk jk2, I don't know the difference between jakarta-tomcat-connectors-jk-1.2.4-src.tar.gz and jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz. I would assume that as jk2 is what the documentation recommends, that the second tar.gz file would be what I need, but it is close to a year older than the former file. 3) Is there in existence anywhere an actual document on how successfully to build jk(2)? Because trying to follow the instructions in the above two tar.gz files would never actually get anything in the source files to build.
