Re: Apache AliasMatch

We use

ScriptAliasMatch ^/IMAGESERVER/(.*) /QSYS.LIB/RJSIMAGE.LIB/$1.PGM

in our product - the caret (^) means the beginning of whatever follows 
the IP address and optional port. The bit in parentheses establishes a 
replacement value for later, specified by a dollar-sigh ($) and an 
ordinal that corresponds to its position in the string.

(Maybe the caret is superfluous - I've seen an example of Alias that, of 
course, would not have the caret, and that has me wondering.)

The URL for the above could be

http://ourIPaddress:port/imageserver/vernspgm?name=vern&date=11/22/2009

This would call program VERNSPGM in library RJSIMAGE and there are 2 CGI 
variables involved.

Does that help? Does it [Alias]Match what you need?

There is also an Alias directive that doesn't use regular expressions at 
all - it's essentially hard-coded.

Is this for CGI? Then ScriptAliasMatch is the thing, because I think 
AliasMatch is for non-scripting - yes, I just read that the "Script" 
versions "designate the target as a CGI script."
