URL Encoding

[kellymandingo]

HI

SEOmoz has finished crawling the site and surprised me with nearly 4k of 301's

all the 301 are on my deal pages

Example of the 301

http://www.economy-car-leasing.co.uk/van-leasing-deals/ford/transit-lease/transit-lwb-el-minibus-diesel-rwd-high-roof-17-seater-tdci-135ps%3D586165

as you can see from the above URL it returns a 404 but the URL is actually sent as below

http://www.economy-car-leasing.co.uk/van-leasing-deals/ford/transit-lease/transit-lwb-el-minibus-diesel-rwd-high-roof-17-seater-tdci-135ps=586165

For some reason SEOmoz crawler is converting the = to %3d and reporting its a 301 even though it returns 404

Is this an error on SEOMOZ part ? or is there an error on my site

Googlebot when i do a fetch as Google bot returns all on with the = sign and every other tool i have tried is ok too

so not sure why SEOMOZ is seeing it different and then adding the URL as a 301

I am hoping this is just a glitch on the report tool part as im struggling since a recent site 301

Kind of answered my own question to a point

The encoding of a = sign converts to %3D (no idea why SEOMOZ is picking this up on its crawl, the 301 is being done by my htaccess because its an upper case D the 301 it 301's  the upper case to lower case then to a 404 page which is not good, i have fixed this but still wonder why SEOMOZ is seeing the %3D instead of an = sign
