I have set up an expression to rewrite my dynamic URLs to static ones. And it almost works 100%...
Here's my expressions:
| Code: |
RewriteRule ^([a-z]+)\.shtml$ stamps/script1.php?ent=$1 [NC,L]
RewriteRule ^([a-z]+)([0-9]+)\.shtml$ stamps/script2.php?ent=$1&set=$2 [NC,L]
|
And they work except for when I have certain pages that begin with "com"
com1.shtml should map to "stamps/script2.php?ent=com&set=1"
It fails, with this log entry:
| Code: |
[Wed Apr 16 16:53:33 2008] [error] [client 127.0.0.1] Forbidden: G:/Spacestamps/com1 doesn't point to a file or directory, referer: http://localhost/com.shtml
|
I suspect that com1.shtml through com9.shtml are somehow reserved in Windows, because those generate forbidden errors. My rewrites for com10.shtml and higher work flawlessly.
Is there any way I can configure Apache to process those rewrites and build my queries? Or am I going to have to write some sort of special case handling for com1.shtml - com9.shtml?
TIA. |

The problem isn't in Apache, but in Windows itself.
com1 (upper or lower case, with or without an extension) is a reserved device name, not a file name.
See Microsoft's note about Naming a File.
| Quote: | | Do not use the following reserved device names for the name of a file: CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed by an extension, for example, NUL.tx7. |
I don't see any way to get around this problem with configuration directives on Windows.
Early in the request processing Apache calls a Windows function to test if each segment of the URI is 1) a "file", 2) a "directory", 3) "doesn't exist".
It is OK if it doesn't exist, mod_rewrite might take care of that in a later step - but if Windows says it is a "device" the request is immediately forbidden.
This all happens before mod_rewrite, so any device name (in any segment of the URI) will never make it to your RewriteRule.

I found a left-handed way around it: I stuck a zero in between:
| Code: | if ($stampset<'10') { $zero='0'; } else { $zero=''; };
... a href='/$issuer$zero$stampset.shtml'
|
which gives me com01.shtml, gets to the point that Apache can rewrite it and works like a charm.
Thanks for your input - I suppose we can mark this closed. |
