Content Engine and PHP WebSites

Hi,
I have Content Engines in a transparent caching scenario. The HTPP traffic being redirected to the CEs are from squid proxies.
Sometimes, for php written sites, when the client tries to access the website or a particular link in a website, instead of getting the site content he gets a popup window asking if he wants to save the content or cancel the operation.
I noticed that this problem does not happen if I force the client browsers to use HTTP1.1 through proxy connections or if ... I clear the cache content (the content engine content).
If I access these sites using a dial-up line this problem doesn't happen. Only from the customer network, where I deployed the transparent caching solution does this happen.
Does anyone have a clue regarding this issue?
Thanks in advance for your attention.
Regards,
Ricardo

Thanks for your reply.
I do not have any rules applied on the CE configuration.
After looking to some sniffer traces I took I suspect that my problem is related with the fact that I have requests made with browsers configured for HTTPv1.0 through proxy connections and others HTTPv1.1 through proxy connections.
When a client browser makes the request using HTTPv1.1 through proxy connections the content will be cached in encoded gzip format.
At a later time when another client, this time using HTTPv1.0 through proxy connections, tries to access the same content the content engine will deliver it encoded ... but the browser does not support it, and a pop-up window appears asking if the user wants to save the content.
So, now I suspect that this has nothing to do with the site itself but only with the requests and responses.
The clients are behind squid proxies.
It is the traffic originated by the squid proxy that is being redirect trough WCCP to the content engine.
I will do additional tests and try to find a way to solve this issue.
Once again Thanks for your reply.
I've you have any additional comments, feel free!
I need it :)

Wacky integration of PIX,Content engine and router

Dear All,
I have got a situation...The situation is
that I have a pix515e, Content Engine and
Cisco 2620xm router...The 3 attachments contain each of the systems configuration..They are arranged in the following way..
There is a 192.168.0.0 network ID running on the PIX inside network which is getting translated by pix to 172.16.1.11-172.16.2.254. The e0 of pix has got an IP address of 172.16.1.7. PIX firewall's gateway is the router's ethernet interface which is 172.16.1.3. I have allowed tcp etc traffic for the inside network.
After PIX there is a content engine 565A which is getting connected via its gigabit interface with IP address of 172.16.1.2 to the network with wccp config.
The router is running 172.16.1.3 on its ethernet interface with the wccp configuration on WAN facing interface..
The problem is that I am able to access the Internet from inside of the PIX.. The PIX is translating perfectly...When the traffic reaches the router, it also translates into public addresses perfectly..The user's are accessing Internet without any problem..and i can see the nat maintained on router and pix..
But the problem is that when i write sh wccp gre on content engine, it doesn't show any activity..This is the problem that content engine is not responding the way it should..
Right now I am lost why the CE isn't working... If anyone has faced this scenerio before then any help will be greatly appreciated...
Hoping for a response which resolves this...
Regards,
Noman Bari

Dear Joerg,
Thank you for your response... That night when I had posted my request for help, I went back to my hotel room, took a shower and focused on CE and router communication and what was configured on them (by some another consultant)...
And then it struck to me that wccp was never enabled on the router in the global config(see the router config in my 1st posting)... once this glitch was removed, everthing now works .. This was never a pix issue bcuz I could see that it was working the way its suppose to work,xlating was happening, people were surfing the web and stuff but the show commands on CE and router weren't showing any activity..
The following link on configuring Cisco Cache Software helped me enormously and I recommend to everyone working on CE..
http://www.cisco.com/en/US/products/sw/conntsw/ps547/products_configuration_guide_book09186a0080087140.html
Through this process I learned a very important lesson though...when you are troubleshooting a problem, never trust the configurations that have been done by the guy before you...start everything from the scratch by going through the documentation..
and ofcourse this extremely useful Cisco Forum also...

Content Engine and L4 Switches

I am network administrator in a big company, the case is as follows:
I have a new Content Engine 590 and I want not to use wccp, I will buy a new cisco L4 switch and want to use it with the engine, some one told me that it is not supported by my engine, is that true or not???
I have a cisco router and I can use wccp but papers from different web sites writes that L4 switching performance is better, is that true???
thanks
A. F.

The feature is code-specific, and the content engine will support L4 switch forwarding. You might want to look at this document to see the sample configuration for this. If you scroll passed the CSS config you will see what the CE configuration will look like.
http://www.cisco.com/warp/public/117/CSS_CEreverseproxy.html
If you weren't interested inL3 WCCP on your gateway router and wanted performance, you might want to look into the L2/mac re-write redirections you can do with a Cat 6K and a CE:

Content Engine 565

I have 2 catalyst 6506 and 2 cache engines. Want to achieve transparent caching(Client have proxy setting on the IE)
I have configured exactly what the user guide has shown.
But I cant see the http traffic begin re-direct to Content Engine.
The http traffic go out directly to the proxy server.
Attached is the config file for one of the content engine and one of the catalyst 6506.

The configuration looks ok to me. You could probably turn on some debugs to see what is happening. Also check the cache engine status. You could use the commands in this document to help you.

Content Engine multicast duration logs

With Content Engines and CDN solution, we deployed a multicast station (for non-live contents). With the transaction logs we were able to log access to the first connection to the content-engine (as a http connection) but for our customer would be useful being able to track connection time of each client to the multicast station. There's a way to handle this?
Thanks

Well I am not sure if this is possible. You could however check the URL that the CE is caching. Here is the link to a document that explains how to do it.

Content Engine + Barracuda Spyware firewall (transparent/intercept proxies)

Hello all.
We are trying to get our WAE-511 content engine and our Barracuda Spyware Firewall 310 to work together.
It seems they interfere with each other because they are both transparent (intercept?) proxies.
What would need to be done/configured (preferably in the Cisco CE) to make the two devices work together?
Would shifting the CE to non-transparent mode help?

check out the following link, hope this helps :

Content Engine on PIX DMZ

Can we place content engine outside interface on PIX DMZ interface. At this moment both the WCCP router and content Engine are on outside. I want to place Content Engine Outside interface on PIX DMZ and then to run WCCP between Content Engine and Outside router.
Thank you.

Yes. You can place the content engine towards the outside interface on PIX. This should work.

I am trying to open a website that is using Microsoft content viewer, and the page does not show. Any ideas on how to view this site using firefox. It works on IE.

I am participating in an online class whose website uses Microsoft Content Viewer to view the class content. The browser opens a new page, but nothing is there. At the top of the tab it says Microsoft Content Viewer, and nothing else. Can anyone tell me how to view my course using Firefox? I would prefer not to use IE, but it works there.

When originally creating the pdf, you would need to choose another pdf conversion setting. In Word if you use the pdf menu, change your settings there: Adobe PDF > Change Conversion Settings. I would use High Quality Print instead. If you use the File > Print method, click the Properties button next to the Adobe PDF printer selection.
For your already created form, you can change the file so your users will not encounter issues. In Acrobat 9, which hopefully is similar in process to 8: Advanced > Preflight > Profile tab > PDF/A compliance > Remove PDF/A information.(You'll have to unsecure your form first).
You can read about PDF/A files in the Help.

Content Engine transaction logs -- monitoring and analysis

At our remote sites there's a local Cisco CE511 to ease our WAN bandwidth. I have been tasked to find a method to gather CE usage for trending and troubleshooting.
From my search on the internet I decided to go with the Webalizer application. I setup the CEs to export their transaction logs every hour to my FTP server. After a test of Webalizer on a log file, it produced a nice HTML report for that hour.
I would like to discuss with anyone on bringing this up to a new level. I would like webalizer to run as a cron job, but the log file names changes every hour. So that's a hurdle I need to figure out. Also keeping track of user web hits is important. I would like to make sure my reports are accurate in reporting what IP address is the top talker.
I hope this will start a productive exchange of ideas. Thanks.

Simple Network Management Protocol (SNMP) is an interoperable standards-based protocol that allows for external monitoring of the Content Engine through an SNMP agent.
An SNMP-managed network consists of three primary components: managed devices, agents, and management systems. A managed device is a network node that contains an SNMP agent and resides on a managed network. Managed devices collect and store management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, access servers, switches, bridges, hubs, computer hosts, and printers.
An SNMP agent is a software module that resides in a managed device. An agent has local knowledge of management information and translates that information into a form compatible with SNMP. The SNMP agent gathers data from the Management Information Base (MIB), which is the repository for information about device parameters and network data. The agent can also send traps, or notification of certain events, to the manager.

Saturation on Content engine CE-565 and Smartfiler log

Hi, with content engine CE-565-K9
we have the following message log on the smartfilter:

I can't see how is limited the thread number on the CE565. So who can explain to me the signification of this log and/or how configring the maximun thread on the CE565.
Thank's

Smartfilter uses a pool of 20 threads for LDAP lookups. What this error indicates is that the number of outstanding LDAP requests has grown to more than 1000 which is the limit supported.

PHP website displays on web server but only text shows on local testing server

Hi, I am not a PHP programmer.
I tried to get the testing server set up in the DW site definition area but was unsuccessful so I am back tracking to first make sure I have a working testing server. So, here is the info:
I took on a new client with a simple PHP site, without any databases.
The site is up and running on the web.
I would like to eventually get it running on my local machine to integrate editable regions for use with Adobe Contribute.
I have latest version of WAMP installed running Apache version 2.2.11 and PHP version 5.3.0
I created a directory in the WAMP "www" project directory and it shows up like it's supposed to when I browse to "localhost"
Problem:
The home page of website displays text but no, images, styles, footer, header, nav links, etc.
Here is the code for the home page:
Welcome This is the content area. This is the content area. This is the content area.
Any help would be greatly appreciated. I have spent many hours on this.
Regards

Hi,
Not sure what you have going on there. One thing I would try is to enclose all your php code within <?php code here ?> not <? code here ?>
Also ADDT does not work fully with php 5.3.0 as this may also be your error. When you say it only shows text do you mean dynamic text values or just text that is not dynamic?

[PHP]
; About php.ini ;
; This file controls many aspects of PHP's behavior. In order for PHP to
; read it, it must be named 'php.ini'. PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; The path in which the php.ini file is looked for can be overridden using
; the -c argument in command line mode.
; The syntax of the file is extremely simple. Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
; Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
; foo = ; sets foo to an empty string
; foo = none ; sets foo to an empty string
; foo = "none" ; sets foo to the string 'none'
; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
; About this file ;
; This is the recommended, PHP 5-style version of the php.ini-dist file. It
; sets some non standard settings, that make PHP more efficient, more secure,
; and encourage cleaner coding.
; The price is that with these settings, PHP may be incompatible with some
; applications, and sometimes, more difficult to develop with. Using this
; file is warmly recommended for production sites. As all of the changes from
; the standard settings are thoroughly documented, you can go over each one,
; and decide whether you want to use it or not.
; For general information about the php.ini file, please consult the php.ini-dist
; file, included in your PHP distribution.
; This file is different from the php.ini-dist file in the fact that it features
; different values for several directives, in order to improve performance, while
; possibly breaking compatibility with the standard out-of-the-box behavior of
; PHP. Please make sure you read what's different, and modify your scripts
; accordingly, if you decide to use this file instead.
; - register_long_arrays = Off [Performance]
; Disables registration of the older (and deprecated) long predefined array
; variables ($HTTP_*_VARS). Instead, use the superglobals that were
; introduced in PHP 4.1.0
; - display_errors = Off [Security]
; With this directive set to off, errors that occur during the execution of
; scripts will no longer be displayed as a part of the script output, and thus,
; will no longer be exposed to remote users. With some errors, the error message
; content may expose information about your script, web server, or database
; server that may be exploitable for hacking. Production sites should have this
; directive set to off.
; - log_errors = On [Security]
; This directive complements the above one. Any errors that occur during the
; execution of your script will be logged (typically, to your server's error log,
; but can be configured in several ways). Along with setting display_errors to off,
; this setup gives you the ability to fully understand what may have gone wrong,
; without exposing any sensitive information to remote users.
; - output_buffering = 4096 [Performance]
; Set a 4KB output buffer. Enabling output buffering typically results in less
; writes, and sometimes less packets sent on the wire, which can often lead to
; better performance. The gain this directive actually yields greatly depends
; on which Web server you're working with, and what kind of scripts you're using.
; - register_argc_argv = Off [Performance]
; Disables registration of the somewhat redundant $argv and $argc global
; variables.
; - magic_quotes_gpc = Off [Performance]
; Input data is no longer escaped with slashes so that it can be sent into
; SQL databases without further manipulation. Instead, you should use the

; - variables_order = "GPCS" [Performance]
; The environment variables are not hashed into the $_ENV. To access
; environment variables, you can use getenv() instead.
; - error_reporting = E_ALL [Code Cleanliness, Security(?)]
; By default, PHP suppresses errors of type E_NOTICE. These error messages
; are emitted for non-critical errors, but that could be a symptom of a bigger

; of uninitialized variables to be displayed.

Did I do anything wrong, is this how it's supposed to work? I googled the error from lighttpd error.log and the only useful information I could find was in polish i think, and unfortunately, i don't speak polish.

ls -l /var/run/lighttpd/
And how are you spawning the php instances? I don't see that in the daemons array anywhere.
EDIT: It looks like the info in that page is no longer using pre-spawned instances, but lighttpd adaptive-spawn. The documentation has been made inconsistent it looks like.
You will note that with pre-spawned information, the config looks different[1].
You need to do one or the other, not both (eg. choose adaptive-spawn, or pre-spawn..not both).

Where to place 2nd and 3rd website's home directories?

In Os X Server 10.4.6, when we activated our first website (the default) it's home directory is /library/webserver/documents
When adding a 2nd and third website to host, should their home directories be children of, or siblings of the original Documents directory?
And when I create them, what's the best way to create them to ensure the permissions are correct?
And for that matetr, what should the permissions be if I'm not using Webdav, and using FTP or SFTP to allow webmasters to update the sites?
I want to be sure the new websites inerit the same features (like running php, weblogs, webmail as the original website.
Thanks!

>When adding a 2nd and third website to host, should their home directories be children of, or siblings of the original Documents directory?
There's nothing special about a web site directory (other than permissions). /Library/WebServer/Documents is just Apple's default suggestion.
However, if you store the other domains in subdirectories of /Library/WebServer/Documents then they'll be accessible under the first domain, which probably isn't what you want.
For example, if you create your second domain in /Library/WebServer/Documents/www.domain2/ then it'll be accessible as http://www.yourdomain.com/www.domain2/
Therefore if you're going to use /Library/WebServer, create siblings, not children of Documents.
>And when I create them, what's the best way to create them to ensure the permissions are correct?
Web content needs to be readable by the 'www' user, and directories need to be executable. This means you can either save your content as owned by 'www' or, more commonly, make sure it's world-readable, that way other users can create and edit the content while apache can still serve it.
>And for that matetr, what should the permissions be if I'm not using Webdav, and using FTP or SFTP to allow webmasters to update the sites?
The user in question would need write access to the content in order to change it, whether locally or remotely. As mentioned above this could be that the content is owned by the user, but world readable, and that's probably the commonest setup.

Content engine 565 - real server relay

hi all,
we have a standalone content engine 565 running acns 5.3.1. we would like to realize something like a live stream 'relay':
we place the ce on the network edge and it receives a live stream (rtsp) directly from a content provider. the internal clients send their rtsp requests for that live stream directly to the ce which answers the requests. one important thing is that we cannot use a proxy configuration, because a proxy config on the client is not possible - meaning that we need to place requests directly (no direct or transparent proxy). in the real subscriber config interface I saw the receiver/transmitter section - is that the right way to go? where can I find config examples or documentation for that issue. on the cisco website I could not find any detailed documentation for real subscriber configs.

thanks for the answer - i realized it rather late. can you help me in configuring this setup? as i said I cannot find any documentation support for such a setup...I would really appreciate any help.
thanks,
daniel
