Apache to Zope/Plone with ProxyPass - how can I get Apache cgi scripts?
by Cormac McClean 22 Jun '04

22 Jun '04

Hi, This is a follow up to an earlier question, which involved trying to access Plone as the front page behind Apache. I got this working thanks to Simon Forster, using ProxyPass and a SiteRoot object. However, I still need to access some cgi scripts from Apache's cgi-bin directory. Is this possible? Here's what I have at the moment: <VirtualHost *> ServerName erebus.ait.ie DocumentRoot "/usr/local/apache/htdocs/zope" ProxyPass / http://erebus:8080/zope/erebus_plone/ ProxyPassReverse / http://erebus:8080/zope/erebus_plone/ </VirtualHost> When I try accessing a cgi script in /cgi-bin, I get a not found error (404). I also tried this: ProxyPass /cgi-bin/ ! thinking that it might override the Proxying and just go to /cgi-bin, but I get an error --- Bad Request Your browser sent a request that this server could not understand. --- I have tried using mod-rewrite and the Virtual Host Monster without ProxyPass, which allows me to access Apache's cgi scripts, but I don't get Plone properly. I wonder is it possible to combine ProxyPass and RewriteRules? Thanks in advance, Cormac.

About multiple-channel publishing...
by Gelin Patrick 22 Jun '04

22 Jun '04

Hi, I would be very interrested to know how to manage multi-channel publishing with Zope because of using Apache as a publish front-end need you to move private pubished resources into public Apache cache... - So how to publish private information efficiently with Apache? - Is SSH a solution? if so, how big is the cache you need? Is it suitable for a community around 25000 users? By the way, do you know any benchmark about performance issue to prove zope optimisation with Apache is a good solution for a portal with multi-channel publishing, i.e. publishing a lot of private information? Thanks for your help.

ANN: VarImage 2.3.2 Released
by Terry Hancock 21 Jun '04

21 Jun '04

Version 2.3.2 includes the large cache-optimization patch written by Eric Pollman which reportedly can improve performance by 10X or more in certain test conditions. I have tested it on Zope 2.5.1 and Zope 2.6.4 (on FreeBSD and Debian Linux platforms, respectively), but it probably works on later Zopes and any platform on which PIL is available. This also fixes a bug with handling width and height attributes, should they be set to strings instead of ints, which avoids some annoying editing problems. Get it from the Narya project at SourceForge: http://sourceforge.net/projects/narya-project Cheers, Terry From the README.txt file: VarImage 2.3 VarImage means "variable image". It provides a way to make on-the-fly modifications to an image in Zope simply by referring to the correct URL. [...] Syntax The URL-command is parsed as a chain of "operations" to be applied to the original image, separated by "." (period). Each operation is specified as an "operator", followed by zero or more "arguments", separated by "_". Arguments and operators must be composed of only letters and numbers ([A-Za-z0-9], note that "_" and "." are not legal because they are used as separators). Other than the fact that floating point values have to use "o" (the letter "o") instead of "." for the decimal point, this works well. Colors are represented by strings, usually as hexadecimal codes, with a prefix of "x" and 6 hexadecimal characters. Component images may be referred to by their unadorned Zope ID, so "myimage/components/mycomponent" is simply "mycomponent". Note that, to be useful, you have to use only letters and numbers in the name of components. Each operation is applied in sequence, to the result of the previous operation, and then the final result is returned. Examples If you have a VarImage "shinobu_jpg", you can get it in an exact size of 100x100 (regardless of the original aspect):: shinobu_jpg/s_100 or 100x50:: shinobu_jpg/s_100_50 or you can thumbnail it into a 70x50 space (the longer dimension will be determined by the specified limit, while the smaller is determine by the image aspect ratio -- i.e. the image will "fit" into the available 70x50 space):: shinobu_jpg/f_70_50 or you can set the horizontal or vertical dimensions:: shinobu_jpg/h_85 shinobu_jpg/v_100 (The above examples are converted from the Version 1 docs). You can also convert the image to PNG or GIF format:: shinobu_jpg/tn_100.png shinobu_jpg/tn_100_200.gif And do color effects, such as black-and-white:: shinobu_jpg/bw or color-multiplication:: shinobu_jpg/mult_x0e5f00.png shinobu_jpg/bw.R.gif Special Commands For a help page with a complete list of all currently understood operators, use:: shinobu_jpg/help If you need to clear the cache and start over for some reason (this is necessary a lot when you're writing a new plugin):: shinobu_jpg/clear_cache [...] How It Works VarImage inherits from Zope's Image and ObjectManager types, so it is an image that also acts as a folder. The folder contains a Temporary Folder named "cache". When you query for a modified image, it first checks to see if the cache already contains the image. If so, it returns that. Otherwise, it uses Python Imaging Library to generate the image, and stores the result in the cache. [...] Writing Plugins It is now trivial to add a plugin operator to VarImage, and you do not need any understanding of Zope to do this. You will need to understand how to manipulate and process images in Python. [...] Author and Licensing Terry Hancock wrote VarImage for Anansi Spaceworks.

The action attribute would be 'results.html' as I suppose it already is. This seems to be an HTML question, not a Zope one. Cheers, Tom P

To: zope(a)zope.org Reply-To: <zope(a)zope.org> I've done something similar to give local users a url and off campus users a url that authenticates the user through the proxy server. At the top of the page I call a python script that receives the REMOTE_ADDR and splits it on the dots and then checks the first two octets of the IP address. If both match then a flag is set to true otherwise it is false. I think I recall getting a script from the Zope Cookbook and used only the part I needed. No security was needed for this page because access to the target urls did the authentication.

Redirecting Search Result
by Michael A. Ruberto 21 Jun '04

21 Jun '04

Hi, I have a Zcatalog search very similar to the one in the Zope book. the page with the search form is in the top frame of a 2 frame page. the code for it was generated by the ZSearch Interface: <form action="results.html" method="get"> Enter query parameters:<br><table> <tr><th>SearchTextIdx</th> <td><input name="searchTextIdx" width=30 value=""></td></tr> <tr><td colspan=2 align=center> <input type="SUBMIT" name="SUBMIT" value="Submit Query"> I would like to have results.html display in the bottom frame instead of the top frame where the search form is. after much looking for answers on zope.org and elsewhere it appears there is not a shred of howto available to help me here. I would greatly appreciate any suggestions - and no I cannot put the search form in the bottom frame ;-) THANKS!!!! Michael A. Ruberto DORTRONICS SYSTEMS INC.
