Content engine 510 - transparent proxy stand-alone

Hello to all,
after studying architecture examples about Content Engine 510, I found that there is two modes:
1) standard proxy
2) transparent proxy
I need the transparent architecture !
But every example about transparent mode seems to include a router or a switch with a particular level of software, that can send http requests to the Content Engine to have cache.
I don't have any of these components.
I simply need to have a Content Engine that receive any kind of IP protocols on one ethernet, and route it to the other ethernet plug, except that if it is http protocol, it will cache the pages.
Is is simply impossible to configure the Content Engine 510 that way ?
Is the transparent proxy mode always requires a router or a switch to give it the http flow ?
If it is possible, where can I find some configuration examples ?
Thanks to help a newbie in content engine...
Olivier

Olivier,
You'll need to have a router running wccp in order to redirect http requests to the cache. Withouth this, the cache has no visibilty of traffic on your LAN.

Dave

  • 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 ?
    Rgds
    Eng Wee

    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.

  • Using Content Engine for SOCKS Proxy

    We have a CE566 integrated with an ICAP server in a proxy role for our network.
    we are experiencing issues with a Java applet that many of our users use with an outside vendor.
    Here are the test results from Sun's Java J2RE development team who we're working with:
    The trace log shows SOCKET connections via ports 80 and 443
    failed.

    Does anyone have any information in regards to using the CE as a proxy in this regards? I have obviously found command language for http; https; and ftp - but nothing for other methods

    The site he's accessing required SOCKS proxy. The ACNS does not support SOCKS.

  • What are the real advantages of ultilizing Teststand test engine as opposed to stand-alone Labview programming

    The real problem that i am having is trying to keep open the VI that is called by Teststand for the user to enter values. Sometimes the window does not even appear to be open. Do i need to add delays.

    hi,
    I guess you do have a while loop in your VI to allow for user input!!
    It might be that the VI front panel is going behind the main panel. In which case you need to make the VI behave as a modal dialog. If you have TestStand 2 then there is an example ModalDialog in the examples folder. If you are still using Teststand 1.0.x then you can get the same example in the Resource Library. Do a search for Modal Dialog.
    Hope this helps

  • Content Engine caching video content?

    I am currently running ACNS version 5.5.11.2 on a CE510 Content Engine. I recently had to replace the unit and when I set up the partitions for the new build, I elected to go with CE510#disk config sysfs 10% cfs 45% mediafs 45%.
    Before the cfs was setup to use the whole box. I was thinking that the mediafs partition would start to cache video content. Does that happen automatically or is there some other setting to make that happen further. How do I determine if it is getting any use?

    A content engine can cache files transfered via ftp but not https [as the content is encrypted].
    It can cache whatever file, including video, audio, ...
    Content routing, content switching are just names.
    They refer to how the traffic will be intercepted and forwarded to the content engine.
    You could simply use a proxy solution and have your users setup their browser to use the content engine as a proxy, or you could transparently intercept http/ftp traffic via a router running wccp, or you could use a Layer7 device like a CSS to intercept the traffic and redirect to the content engine.

    Hi Deepak,
    Thanks for Reply.
    But in /home/sapcs/conf/http.conf file its already maintained like this, sending you some part of httpd.conf file
    Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the #<VirtualHost> # directive.
    Change this to Listen on specific IP addresses as shown below to  prevent Apache from glomming onto all bound IP #addresses.
    Listen 1090
    User/Group: The name (or #number) of the user/group to run httpd as.
    It is usually good practice to create a dedicated user and group for
    running httpd, as with most system services.
    User sapcs
    Group sapsys

  • I have trouble in building stand-alone application, "you must intall Labview run-time engine on any computer on which you want to run this application"

    I have installed the LabVIEW 7.0 run time engine and checked all in the advanced setup on the installer setup slide. but I still get such a message saying that the target computer needs to have LabVIEW 7.0 run-time engine. What I want is a real stand-alone application even without having labview ... I used to think that's due to my program contains MATLAB nodes. But this is not true, since even without Matlab, it's still wrong. Please help, thanks!!!

    As was stated elsewhere, you have the option of building the runtime engine into your application when you build it. However, you can also create a "runtime engine application" by simply opening the application builder and doing a build without adding any source code files. The result is a small program (named lvrt.exe) that can run any LabVIEW code--whether or not its built into an executable.
    Such an application can be helpful if you are wanting to install several LV-based applications on the same computer in that it reduces the amount of redundant code on disk. All you have to do is make sure that Windows on the target computer associates the llb and vi file extensions with the runtime engine program.
    It can also be helpful during testing to run test code that isn't built into an executable.

  • Should the Cisco Content Engines be used as a proxy appliance

    I am pretty sure it is but just need some feedback on past experiences. Customer would like to by a Cisco product for Web filtering/proxy.
    or is it strictly used to help with web base applications.

    HI,
    the CE is basically able to check every request it supports. If you are using 3rd level products like smartfilter, websense or webwasher you can use the features of those products to supress/forbid certain requests(i.e MSN etc.)

  • May I install a stand-alone Adapter engine for MI?

    I wonder if I can install a stand-alone Adapter engine (i.e. JAVA SE)  for MI?
    Points guaranteed. Thanks!

    Hi,
    no, that is not the usual way of handling data with MI.
    Well, MI exchanges data with the Middleware and the backend via SyncBO or Generic Sync. SyncBO is a data container that does the complete delta handling for example. The connection will be: XI receive data from an external system and stores that data in R/3. Then the SyncBO retrieves this data via GETLIST and GETDETAIL handlers and then the data comes down to the device with the next sync.
    BUT: the thing above is extremely drilled down - because of that it is only seen as a general answer. To discuss it more in depth, feel free to get in touch with me. The question I have in mind is till: what do you want to do with the XI connection.

  • Use of outgoing proxy with content engine

    Hi All,
    I'm experiencing problems using the "outgoing proxy" feature with a content engine running ACNS 4.03.
    When this feature is enabled, it takes a long time to get the "execute or save to disk" popup window in the web browser, but when I get it, the file is downloaded in a few seconds.
    It seems like the CE waits for the file to be completely retrieved before delivering it to the client...
    This is not service impacting when this is a small file, but when the file is bigger than 1MB, the browser fails with a timeout.
    Can anyone help ?
    Thanks,
    Phil.

    4.01b1 code had a hardcoded proxy timeout value of 300 micro seconds. The ability to set this value was introduced in 4.03 to address symptoms like the one you are describing when the CE is not able to connect to its upstream proxy within this time constraint. (also documented the following bug : CSCdv36226 - "Need CLI to configure connection timeout for outgoing proxy"
    The fix was implemented with the addition of the follwoing command to set this value: 'http proxy outgoing connection-timeout' command:
    590(config)#http proxy outgoing connection-timeout ?
    <200-5000000> Timeout period for probing outgoing proxy servers in microseconds
    590(config)#
    I hope this helps!

    It's difficult to tell from here what graphics you are referring to, but if you use the Dialog Controls, then the Operating System you run your application on with automatically place its default controls on the Front Panel. For instance, if you run it on XP, you will get the native XP controls. If you run it on Mac OS X, you see native OS X controls. This may help you out on that.
