RE: [squid-users] Squid Error Pages

Hi Brie,

I have just gone through a similar scenario myself. So I might be able to help.

You can get rid of the "Generated by.." signature by including the %s variable in your error page. As soon as you include the %s somewhere the page, "Generated by..." line no longer appears.

This means that your error pages *must* include the word "squid" somewhere. If you want to hide it you can either alter the code and re-compile, or you could always change the colour of the text to match the background, for example:

<FONT COLOR="#FFFFFF">%s</FONT>

On a white background will allow you to hide the signature. You will still see "squid" if you look at the HTML source using your browser, but it's a quick fix if your not up to editing code.

I believe that the FTP and Gopher signatures have to be removed by altering source and the above trick won't work.

Like Henrik said, the images have to be served from a web server.

I am taking a guess that you have installed Apache, but put the images in the same folder as your error pages. That won't work. Put the images in your Apache root/htdocs/www folder. For example if you have a server called squid1.mydomain.com, and your htdocs folder is /var/www. Created a folder called images in there, and place all your images in /var/www/images.

You should be able to see the images by visiting http://squid1.mydomain.com/images/yourimage.jpg in a browser.

This is the same URL you would include in your ERR_ pages too.

Finally, if you change the location of the error pages using the error_directory variable, don't forget to tell squid to pick up the change using squid -k reconfigure.

Hope some of this information helps.
