Another ProxyPass issue :(

Me again...

 

 

I've hit another issue with the ProxyPassv10 iRule...

 

 

Currently, we've got several VIP's set-up using the ProxyPass irule.

 

One of these VIPs is set-up as follows:

 

 

list /ltm virtual TfGM_CMS.app/service.card.co.uk_https

 

ltm virtual TfGM_CMS.app/service.card.co.uk_https {

 

app-service /Common/TfGM_CMS.app/TfGM_CMS

 

destination 172.16.26.11:https

 

ip-protocol tcp

 

mask 255.255.255.255

 

pool TfGM_CMS.app/TfGM_CMS_pool

 

profiles {

 

HTTP_Rewrite { }

 

TfGM_CMS.app/cmsws_gmpte_card_co_uk_ssl {

 

context clientside

 

}

 

oneconnect { }

 

stream { }

 

tcp-wan-optimized { }

 

wan-optimized-compression { }

 

}

 

rules {

 

ProxyPass

 

SplunkHTTP

 

CatchErrors

 

HeaderStripping

 

MaintenancePage

 

HandleErrors

 

ClientSSLVerification

 

}

 

snat automap

 

vlans-disabled

 

}

 

 

The data-group used by the ProxyPass rule on this VIP contains:

 

list /ltm data-group internal ProxyPass_cmsws

 

ltm data-group internal ProxyPass_cmsws {

 

records {

 

/CMSBureauWebService/CMSBureauWS {

 

data /CMSBureauWebService/CardBureauService

 

}

 

/CMSBureauWebService/CardBureauService {

 

data /CMSBureauWebService/CardBureauService

 

}

 

/CMSWebPortalService/CardRenewalWebPortal_2_0 {

 

data /CMSWebPortalService/CardRenewalWebPortal_2_0

 

}

 

/CMSWebPortalService/VoucherRedemptionService {

 

data /CMSWebPortalService/VoucherRedemptionService

 

}

 

/CMSWebPortalService/WebPortalService {

 

data /CMSWebPortalService/WebPortalService

 

}

 

}

 

type string

 

}

 

 

RewriteResponsePayload is set to a value of 2, and the VIP has a Stream profile attached.

 

However I'm still seeing the following errors logged on making requests:

 

Feb 17 15:50:04 tmm3 info tmm3[9382]: Rule /Common/ProxyPass : VS=/Common/TfGM_CMS.app/service.card.co.uk_https, Host=service.card.co.uk, URI=/CMSBureauWebService/CMSBureauWS: Error setting stream expression (). If you enable static::RewriteResponsePayload, then you should add a stream profile to the VIP. Else, set static::RewriteResponsePayload to 0 in this iRule.

 

 

If I enable verbose logging, I get:

 

Feb 17 15:50:04 tmm3 info tmm3[9382]: Rule /Common/ProxyPass : Processing HTTP_RESPONSE at Priority 900.

 

Feb 17 15:50:04 tmm3 info tmm3[9382]: Rule /Common/ProxyPass : VS=/Common/TfGM_CMS.app/service.card.co.uk_https, Host=service.card.co.uk, URI=/CMSBureauWebService/CMSBureauWS: $stream_expression_cmd: STREAM::expression "@https?://service.card.co.uk/CMSBureauWebService/CardBureauService@https://service.card.co.uk/CMSBureauWebService/CMSBureauWS@ @https?%3A%2F%2Fservice.card.co.uk%2FCMSBureauWebService%2FCardBureauService@https%3a%2f%2fservice.card.co.uk%2fCMSBureauWebService%2fCMSBureauWS@ @/CMSBureauWebService/CardBureauService@/CMSBureauWebService/CMSBureauWS@ @%2FCMSBureauWebService%2FCardBureauService@%2fCMSBureauWebService%2fCMSBureauWS@", $stream_enable_cmd: STREAM::enable

If you enable static::RewriteResponsePayload, then you should add a stream profile to the VIP. Else, set static::RewriteResponsePayload to 0 in this iRule.

 

 

I cant see any issues with the STREAM::expression value of the STREAM::cmd...

 

 

Any ideas what could be causing the above error?
