We have a mod_proxy (2.0.54) front-end proxying to a back-end MS IIS server. One type of URL that we use is causing problems because mod_proxy is decoding an encoded comma in the URL as it proxies the request to the back-end (we determined this with a packet sniffer): between browser and mod_proxy: http://www.company.com/item-01-A1263%7E23334%2Cz831%7E238.asp between mod_proxy and back-end server: http://www.company.com/item-01-A1263%7E23334,z831%7E238.asp As you can see, mod_proxy is decoding ONLY the comma (%2C), which is causing our back-end server to return a 404. Is there a workaround for this in Apache? I'm familiar with AllowEncodedSlashes (which we also have set On), but it seems like there should be an AllowEncodedCommas. thanks for any help and guidance.
