CE HTTP 1.1 and Cache Control

Hi all,
I have two questions concerning CE and HTTP 1.1:
1) Does anyone know what happens on a Content Engine if a web server uses the HTTP 1.1 Cache-Control directive with the value PUBLIC?
How long does the object remain in cache?
2) What happens if I set http max-ttl in global configuration? Does this overwrite the Cache-Control directive?
Thanks in advance
Fausto

I have noticed that when the cache-control directive set to no-cache="set-cookie", the Cache Engine receives incoming HTTP 1.1 Requests, but there is no hit in the cache. Wondering why the Content Engine fails to cache this? I haven't tried the value public.

JRE Cache ignores the "Expire" and "Cache-Control: no-cache" directives.

My applet is using HttpURLConection to retrieve data from a server with Caching enabled. The cache contents are "revalidated" (via "if-modfied-since") each time the applet is started. However, subsequent requests to retrieve the same resource are always read from the cache with no validation even if the resource has expired.
The server is sending a valid "Expires:" tag and "Cache-Control: no-cache" tag in the response; but, the JRE refuses to recheck for an updated version of the resource even after the file has expired.
The JRE does seem to understand the "Cache-Control: no-store" tag; but, this is inefficient (no caching at all) when I'm tring to get it to not refetch the resource unless there's a change. Is there some other tag that the JRE is expecting to see?

I have a similar problem except that I want my pages to not cache at all. The server is setting the Cache-Control: max-age to 0 and the Expires to "now" but JRE seems to ignore these settings, but only sometimes. Sometimes pages are fetched from cache and sometimes from the server.
In my applet I'm using a normal URLConnection like this:
URLConnection uc = new URL("http://<server>/method").openConnection();
uc.connect();
InputStream is = uc.getInputStream();
is.read();When my request headers look like this:
accept-encoding: gzip
Host: <server>
Cache-Control: no-cache
Pragma: no-cache
User-Agent: Mozilla/4.0 (Windows XP 5.1) Java/1.6.0_13
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alivethe page will not be cached and is requested again but this time without the accept-encoding, Pragma and Cache-Control. The adding (and removal) of the headers seems to happen inside the JRE, though. I'm not explicitly setting them.
The response header of the first request looks like this:
HTTP/1.1 200 OK
Date: Wed, 20 May 2009 12:55:07 GMT
Server: Apache/2.2.11 (Win32) mod_jk/1.2.26 PHP/5.2.8
Cache-Control: max-age=0
Expires: Wed, 20 May 2009 12:55:07 GMT
Vary: User-Agent,Accept-Encoding
Content-Encoding: gzip
Keep-Alive: timeout=120, max=79
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html;charset=iso-8859-1When the request is made with this header:
User-Agent: Mozilla/4.0 (Windows XP 5.1) Java/1.6.0_13
Host: <server>
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-aliveThe response headers looks like this:
HTTP/1.1 200 OK
Date: Wed, 20 May 2009 12:55:07 GMT
Server: Apache/2.2.11 (Win32) mod_jk/1.2.26 PHP/5.2.8
Content-Length: 1016
Cache-Control: max-age=0
Expires: Wed, 20 May 2009 12:55:07 GMT
Vary: User-Agent,Accept-Encoding
Keep-Alive: timeout=120, max=83
Connection: Keep-Alive
Content-Type: text/html;charset=iso-8859-1And in this case the JRE sometimes fetches the request from the server and sometimes from cache. I have not been able to determine how the JRE decides to refresh, or why it sometimes sends an accept-encoding and Pragma header and sometimes not.
any help would be appreciated.

Disable Pagma and Cache-Control headers in SunOne WebServer 6.1

Hi,
I want the [Pragma] and [Cache-Control] headers completely disappear from SunOne WebServer 6.1 JSP responses (like the SunOne WebServer 6.0 SP8, http/1.1 but no [Pragma] and [Cache-Control] headers), can I achieve this?
Thanks,
Harry

Hi Harry
Do you mean that WebServer 6.0 SP8 provide a way to disable these two attributes? If so, that will be a regression issue for WS6..

Cache engine http transparent proxy and caching

Hi..
My customer some GPRS user in which they couldn't control proxy setting of the web browser.
Is it possible to configure on a cache engine such that when these users access the Internet, they will be intercepted by the cache engine. THe cache engine then forwards the request to a proxy server and out to the Internet ?

It is possible to configure the cache engine to provide access to the users. The following URL shows an example on how to configure the Cisco Cache Engine for transparent caching using the Web Cache Coordination Protocol (WCCP).

This scenario is pretty similar to your requirement. Hope this helps.

Selective Cache-control in the web server

I am using weblogic 8.1 as the app server and Sun one 6.1 as the web server
In my obj.conf of the web server we have this
PathCheck fn="set-cache-control" control="private"
This caches all the pages.
But I don't want some pages to be cached in our site.
For this, I tried setting "no-cache" for the "Cache-control " of the response hedear, in corresponding jsps. But the webserver configuration is overriding this.
This configuration set in the webserver should be applicable for all the modules except for some urls .
can anybody tell me how to make this selective cache-control configuration in the obj.conf of sun one web server.
or if there is any way to prevent the set up in jsp from being overridden this webserver ?
Also it would be great if anybody can explain, what are the services handled by the web server and the the app-server and how they interact with each other....

It's unfortunate that JSPs running in WebLogic can't override the default Cache-Control directives in Web Server. That's probably a bug in the WebLogic plugin. (It is possible for JSPs running directly on Web Server to override the default Cache-Control directives.)
As with any obj.conf directive, you can configure Cache-Control directives on a path-by-path basis. For example, the following would set Cache-Control: no-cache for /foo/*.jsp and Cache-Control: private for all other URIs:<Object ppath="/foo/*.jsp">
PathCheck fn="set-cache-control" control="no-cache"
</Object>
<Object name="default">
PathCheck fn="set-cache-control" control="private"
</Object>Information on obj.conf syntax, including how to configure separate objects for separate paths, can be found in the Syntax and use of obj.conf chapter of the NSAPI Programmer's Guide at http://docs.sun.com/source/817-6252/npgobjcn.html.
I'm not sure what you mean by "what are the services handled by the web server and the the app-server and how they interact with each other". However, it's worth noting that Sun ONE Web Server 6.1 is fully capable of running JSPs by itself; there's no need for a separate WebLogic server.

Cache-Control in OC4J

We had very typical problem in our web application.
We are using Oracle AppServer 10.1.2. on Sun Solaris with Web-Cache Enabled.
When we are trying to access the pages the response object contains multiple Cache-Control headers, though we have not explicitly added through our code. Can any one tell me how to delete the response headers through code or at server settings. I have tried with "reset()" but of no use.
Because of this cache problem we are not able to generate the reports but the same it working with Firefox browser.
Thanks in advance.

Specific CACHE-CONTROL abilities?

This may be more of an actual server setting, but I thought I
would check and see if anyone came up with a way to do this through
straight CF coding.
On sites that require time-sensitive updates, we always use
the CFHEADER and CACHE-CONTROL settings ... it works very well, but
I am hoping to make this even more dynamic.
When you use cache-control in its default format, it causes
EVERYTHING on the page to not be cached and therefore reloaded.
What I am wondering is if there is a way to code CACHE-CONTROL so
it will still allow images to be cached, but not the actual HTML
page code. Reloading images all the time is not always necessary
and it would be nice to save bandwidth wherever possible.
Since caching is done by the browser, I am surprised there is
no way to specify what objects can be cached and what cannot with
these tags; so I am hoping I am just overlooking something.
Thanks in Advance.
IIS6:Win2003:CFMX7

This isn't really an answer, but you could try looking into
serving the images from a different domain and setting cache
headers on the web server, then for the page set different cache
headers that expire immediately. Untested, Untried and just
throwing it out there.
ie
http://images.mydomain.com
http://www.mydomain.com
I get the idea from Yahoo's YSlow plug in for firefox which
rates the page, and one of the ratings is for CDN (Content Delivery
Network), try googling that.
Sorry can't be of any more specific help.

Weblogic setting Cache-control: no-cache?

I have a servlet filter that sets the Cache-control http header to "max-age=30" for static files such as *.css but in the end weblogic sends the value "no-cache".
When the browser asks for the same static file again weblogic responds with http 304 and Cache-control "max-age=0" thus overriding my filter again.
Is there any way to change the client side caching in weblogic (10.3.4)?
(btw the servlet filter works in tomcat)

Hi,
1. response.setHeader("Cache-Control","no-cache");
This is used to prevent the browser from caching your dynamic content generated by a JSP or Servlet.
You set this attribute in the HTTP header of the response object which would tell the browser not to cache this content. So everytime you request the page again, the browser would make a new request, instead of showing you a cached page.
2. response.setHeader("Location", "error.html");
This is called redirecting. "Redirecting" is sending a response from your servlet to the browser telling the browser to go to a new location(make a new request)
The standard way to do this response.sendRedirect(String);

Cache-Control and Accept-Encoding support in Adobe AIR HTML Component

I am evaluating Adobe AIR's HTML component and trying to figure out what is supported.
I built the AIR app and had it point to www.google.com
I notice that the requests to fetch JS,CSS from Adobe AIR do not include Accept-Encoding: gzip header.
Does Adobe AIR's HTML Component support Accept-Encoding : gzip header ?
I also noticed that even though the content served with far futures expiry, i.e. has Cache-Control: maxage={value} subsequent requests are being made and content is not served from the browser's cache.
I observed this accross the app restarts.
Can someone please clarify support of the two above Http headers ?
Thank you.

Prolem with Cache-Control:max-age http header

Hello
It seems that safari do not take into account Cache-Control:max-age=31536000 http header.
Sending this header to the browser I would expect that safari will not ask the server for these resources before current date + one year.
It's the way IE and FireFox are working but safari is asking the server for these resources every time my html page is loaded (see http requests below).
Server returns a 304 status to indicate that the resource is not modified.
Does somebody have an idea about this strange behaviour?
I'm surprise that Safari do not respect RFC specifications.
Is there a settings to enable Cache-Control ?
Perhaps I forgot safari's specific headers..
Thanks

HTTP Cache control / GZIP compression

Hi,
is it possible to add / enable cache control / compression in Connect Pro (7 or 8)? If so, how?
I suspect we'll have to tweak the underlying http server for it but I'd like to know if this is documented somewhere and if it's supported. Especially, we'd like to
- add / configure Cache-Control http headers
- add / configure Expires http headers
- activate GZIP/Deflate compression
If this isn't something Connect offers out of the box, any recommendations for proxy servers to put in front of Connect and things to watch out for?
Thanks,
Dirk.

Thanks. We solved it by adding a custom Servlet Filter to the web.xml.

Lenovo U310: Clean Windows 7 Installation Guide (including Rapid Start and Caching)

Hi there,
this is the first time that I am writing such a guide/tutorial/whatever you may call it – there are probably better ones, but though not being a total computer noob, it took me almost one week to get this pretty (now again) little beast running again. So hopefully this helps some others to avoid such stupid downtimes.
A brief overview on what has happened to my original win 7 Home Premium:
As some may know, this laptop is very well usable as a “Hackintosh” called Macbook clone. So that’s what I did. It turned out to be nice, but I wanted to go back to Windows after a while, using a clean W7 Pro installation to start over. Actually an easy task, format all drives, install Windows, be happy. Just as I had been doing this for years. Unfortunately, it turned out to be a real challenge. First, I couldn’t “see” my drives during installation (and thus not install), then I got random errors during installation aborting it at different points and finally rapid start and caching didn’t work. Every time I tried to activate them (after Win installation), it crashed my PC. I even found an (official Lenovo!) guide stating to install W7 on the SSD, which worked, but sucks due to space limitations. Oh and another very nice thing: The SSD showed up during WIN installation (but not the classical hard drive) stating it was about 60 GB. So as you can see, I have had a lot of different tries and errors. Why I didn’t use Lenovo Easy Recover? As said before, I erased all partitions…
Before we start: If you have a good Windows running on the Laptop, do yourself a favor and disconnect the RAID 0 disks using the Intel Rapid Storage Application before(!!!) proceeding. It will make things much easier. And don’t forget to get all you data on an external drive or something.
Ok, now let’s start.
1.)    Prepare a USB Stick with the following driver
         http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21730 (choose f6flpy-x64.zip If you’re running a
         64-bit system (standard nowadays), take f6flpy-x86.zip if it is a 32-bit Windows, just download and copy them
         into the stick’s root directory) and plug this stick in one of the left side USB ports.
2.)    You’ll need Win 7 on either a DVD (plus external drive, for sure) or (bootable) USB stick
3.)    Connect your drive/stick (with W7) to the right side USB port.
4.)    Switch the computer on, immediately hit FN and F2. That will open the BIOS.
5.)    In the BIOS, navigate to the very right section (“save and exit”) and navigate the cursor to “load setup defaults”.
         Hit enter to approve.
6.)    After that, go to the “boot” tab and disable UEFI-boot.
7.)    Next, go one more tab to the left and set the controller setting to RAID (NOT AHCI or Compatible!!!).
8.)    Navigate the cursor down to “Intel Rapid Start” and hit enter. A submenu will pop up-
9.)    Disable the first entry in that window, that will make the rest be disabled as well.
10.) Navigate to the very right tab, this time hit save and exit.
11.) The PC restarts.
12.) Immediately hit FN and F12 to open the boot selection menu. Select to boot from your W7 DVD drive or USB
        stick.
13.) Click yourself through the whole process of installing Windows 7 until the page comes up where you will have
        to select where to install it.
14.) Click on “load drivers” and after a few seconds your downloaded driver should be there. Click ok to use them.
        Please do this step even if you can see your drives (SSD Disk 0, 32 GB and HDD Disk 1, 465(<-?) GB) as you
        would expect them – otherwise you’re very likely to get an error during the install process.
15.) Now erase all partitions on both drives and select the HDD as the drive to install W7 to – NOT THE SSD!!!!!
        Seriously, don’t choose the SSD.
16.) Windows will probably say that some extra partitions are necessary and so on, click ok and install Windows.
17.) After the installation has finished and you see your Desktop, I suggest you to proceed with the next steps in the
        following order to see as early as possible if you are on the right way.
18.) Install the Chipset driver, restart.
19.) Install the Intel Rapid Storage “driver” and check the box where it asks to additionally install the control center.
        Reboot.
20.) Go into BIOS (FN and F2) and enable Intel Rapid Start (the one you disabled in Step 8 and 9)
21.) Boot into Windows.
22.) Click on the Windows button, type cmd and right klick on the cmd.exe, select to run it as Admin.
23.) Now you’ll create a hibernation partition on the SSD. (which by now should be completely empty as we’ve
        deleted all partitions in step 15)
24.) In the command prompt that we have just opened, type: (without quotas, for sure)
“diskpart” and hit the enter button
“list disk” and hit the enter button
Now you should see your ssd as disk 0 and your hdd as disk 1
If your ssd is disk 0 (that would be standard), write “select disk 0”, otherwise write: “select disk 1”, and hit the enter button.
Now write “create partition primary size=4096” and hit enter again. [if you have 4GB of ram, type 4096, if you have 8 GB of ram, use 8192]
Now write “detail disk” and hit enter to see the volume number behind the volume that we have just created (it is 4 GB or 8 respectively, should be easy to find), in my case that was “2”
Now type “select volume 2” if your 4 or 8 GB volume has number 2 as well, otherwise use the number you found out in step f. Hit enter.
Finally, type: “set id=84 override” and hit enter for one last time.
It should now say back that the id has been set successfully.
Exit the command prompt. (close)
25.) Reboot
26.) Install the Rapid Start driver. Reboot.
27.) Open the Intel Rapid Storage Application.
28.) Click on accelerate and approve the settings. Two RAID’s will be created. Reboot.
29.) Install the remaining drivers, have fun with Windows Update and that’s it!
Good luck to all of you… And hey Lenovo - wouldn't that have been your job after all these posts showing your costumers in trouble? Just my two cents...
If you want, you can now turn on UEFI-boot in BIOS.
PS: If, after installing all drivers, you happen to see one unknown device in your device manager – this one belongs to Lenovo Connect Software that came with your Laptop. (Updates FB, Email etc when PC is in sleep mode) If you install Lenovo Connect it’s going to be fine, however, I would not recommend it as it is said to use a lot of energy and cause some other problems. So just live with it, your PC is totally fine without it.
Kind regards from Shanghai

Seriously guys, I can't use my 3 days old laptop. Some help would be mostly appreciated. At this point, the network connection issue doesn't show up anymore, it's just a blank screen after reboot. I reinstall windows and do it all over again just to achieve the same result.
Now couple of things caught my attention: as I load the "6flpy-x64.zip" driver from step 14, I get a message saying I need to install signed drivers, because unsigned ones are likely to mess up the system.
Secondly, I could not find any Rapid Storage Technology drivers for Windows 7 (particularly for U310 model), so I use the Windows 8 ones (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS031455), which seems a silly thing, yet I know of no alternatives.
Could it be any of these issues to cause my problem? Or smth else? Please help!
